History of StatisticBy the 18th century, the term "statistics" designated the systematic collection of demographic and economic data by states. In the early 19th century, the meaning of "statistics" broadened, then including the discipline concerned with the collection, summary, and analysis of data. Today statistics is widely employed in government, business, and all the sciences. Electronic computers have expedited statistical computation, and have allowed statisticians to develop "computer-intensive" methods. The term "mathematical statistics" designates the mathematical theories of probability and statistical inference, which are used in statistical practice. The relation between statistics and probability theory developed rather late, however. In the 19th century, statistics increasingly used probability theory, whose initial results were found in the17th and18th centuries, particularly in the analysis of games of chance(gambling). By 1800,astronomy used probability models and statistical theories, particularly the method of least squares, which was invented by Legendre and Gauss Early probability theory and statistics was systematized and extended by Laplace; following Laplace, probability and statistics have been in continual development. In the19th century, social scientists used statistical reasoning and probability models to advance the new sciences of experimental psychology and sociology; physical scientists

used statistical reasoning and probability models to advance the new sciences of thermodynamics and statistical mechanics. The development of statistic was closely associated with the development of inductive logic and the scientific method Statistics is not a field of mathematics but an autonomous mathematical science, like computer science or operations research. Unlike mathematics, statistics had its origins in public administration and maintains a special concern with demography and economics. Being concerned with the scientific method and inductive logic, statistical theory has close association with the philosophy of science; with its emphasis on learning from data and making best predictions, statistics has great overlap with the decision science and microeconomics. With its concerns with data, statistics has overlap with information science and computer science.

Statistic Today During the 20th century, the creation of precise instruments for agricultural research, public health concerns (epidemiology, biostatistics, etc.), industrial quality control, and economic and social purposes (unemployment rate, econometrics, etc.) necessitated substantial advances in statistical practices. Today the used of statistic has broadened far beyond its origin. Individuals and organizations use statistics to understand data and make informed decisions throughout the natural and social sciences, medicines, business, and other area. Statistics are generally regarded not as the subfield of mathematics but rather as a distinct, allied, field. Many universities maintain separate mathematics and statistic departments. Statistic is also taught in department as diverse as psychology , education and public health.

(iii) Effect of long time consumption of packaged drinks on our health.  a) Tooth Decay: All soft drinks are acidic which corrodes the teeth by eroding its enamel. The high amount of sugar consumed through soft drinks lead to the development of bacteria that attack the teeth thus aggravating dental problems. People who drink three or more glasses of aerated drinks (gaseous drinks) daily have much higher chances of dental decay, fillings and teeth loss. Therefore, soft drinks contain acid and sugar that corrode and destroy the teeth in one shot.b) Obesity: Soft drinks are mainly composed of filtered H2O, artificial additives and refined sugar. Thus, they lack nutritional value and only add up calories through their refined sugar; therefore, they make you gain weight. But is shifting to "Diet Soft Drink" the solution? The fact is that diet soft drinks contain aspartame (an artificial low-calorie sweetener). Although aspartame does not add up the calories it makes you feel hungrier and crave for food. The Food and Drug Administration (FDA) no longer allows foods containing aspartame to be labeled as "weight reduction product ". Now it insists to label these products simply as "Diet Drink" or "Diet Food ". Research also shows that aspartame causes migraines, dizziness and more over it reduces your memoryIt has been experimentally proved that soft drinks are one of the prominent reasons for obesity. 15

The weight gain is directly related to the amount of soft drink that a person takes in. With every single can, people unknowingly add many extra calories to their body weight.

c) Diabetes :Another very common effect of soft drinks is diabetes. With every can of soft drink, people add large amount of sugar in their body. Long habitual intake of soft drinks can lead to ineffective insulin production from pancreases which consequently affect the sugar level in the body. This further leads to diabetes.d) Osteoporosis: It has been proved that frequent consumption of soft drink can lead to weakening of the bones and osteoporosis. Soft drinks impair the calcification of the growing bones in children.e)Kidney stones: his fact may shock you, but is quite true. Researches have proved that constant and habitual intake of soft drink can lead to kidney stones formation. This happens because of the acidic and mineral radical balance. The body tries to buffer the acidity caused by the soft drinks with the calcium from the

bones. This leads to calcium erosion, which ultimately gets settled in the kidney in the form of stones.

f) Indigesdtion:Soft drink also leads to impaired digestive system. Soft drink contains phosphoric acid which competes with the hydrochloric acid present in stomach and affects its functioning. The ineffectiveness of stomach leads to undigested food which further causes indigestion and gassiness.

g) Dry throat :Soft drinks cause dehydration in the body. Both the sugar and caffeine components of soft drinks are dehydrating agents. They both lead to excess urination, which makes you thirstier than before.

h) High blood pressure: Soft drinks have strong caffeine content. Caffeine causes irritability, restlessness, tension, high blood pressure, excessive urination and other side effects. It is also believed that soft drinks increase blood pressure. Some studies also claim that soft drink has harmful effects on liver.

The sweetener used in soft drinks is Aspartame. It is 200 times sweeter than normal sugar and is far more harmful with many side effects.Next time, when head towards the refrigerator or a store

16

to satiate your thirst with a can of soft drink, make sure you remind yourself of all the side effects that gulping down the beverage will bring forth.

(b)(i) Golden RatioThe golden ratio has fascinated Western intellectuals of diverse interests for at least 2,400 years. According to Mario Livio: Some of the greatest mathematical minds of all ages, from Pythagoras and Euclid in ancient Greece, through the medieval Italian mathematician Leonardo of Pisa and the Renaissance astronomer Johannes Kepler, to present-day scientific figures such as Oxford physicist Roger Penrose, have spent endless hours over this simple ratio and its properties. But the fascination with the Golden Ratio is not confined just to mathematicians. Biologists, artists, musicians, historians, architects, psychologists, and even mystics have pondered and debated the basis of its ubiquity and appeal. In fact, it is probably fair to say that the Golden Ratio has inspired thinkers of all disciplines like no other number in the history of mathematics. Ancient Greek mathematicians first studied what we now call the golden ratio because of its frequent appearance in geometry. The division of a line into "extreme and mean ratio" (the golden section) is important in the geometry of regular pentagrams and pentagons. The Greeksusually attributed discovery of this concept to Pythagoras or his followers. The regular pentagram, which has a regular pentagon inscribed within it, was the Pythagoreans' symbol.Euclid's Elements (Greek: Στοιχεῖα) provides the first known written definition of what is now called the golden ratio: "A straight line is said to have been cut in extreme and mean ratio when, as the whole line is to the greater segment, so is the greater to the less." Euclid explains a construction for cutting (sectioning) a line "in extreme and mean ratio", i.e. the golden ratio. Throughout the Elements, several propositions (theorems in modern terminology) and their proofs employ the golden ratio. Some of these propositions show that the golden ratio is an irrational number. The name "extreme and mean ratio" was the principal term used from the 3rd century BC until about the 18th century. The modern history of the golden ratio starts with Luca Pacioli's De divina proportione of 1509, which captured the imagination [citation needed] of artists, architects, scientists, and mystics with the properties, mathematical and otherwise, of the golden ratio. Michael Maestlin, first to publish a decimal approximation of the golden ratio, in 1597.The first known approximation of the (inverse) golden ratio by a decimal fraction, stated as "about 0.6180340," was written in 1597 by Michael Maestlin of the University of Tübingen in a letter to his former student Johannes Kepler. Since the twentieth century, the golden ratio has been represented by the Greek letter Φ or φ (phi, after Phidias, a sculptor who is said to have employed it) or less commonly by τ (tau, the first letter of the ancient Greek root τομή—meaning cut).

22

Pyramid -the stability of the drink packaging will be more stable because the base area larger-the shape of the drink packaging become more unique because it’s rarely found in the market.

-the cost of packaging material will be higher because more total surface area required.

Cone -the stability of the drink packaging will be more stable because the base area larger-the shape of the drink packaging become more unique because it’s rarely found in the market.

-the cost of packaging material will be higher because more total surface area required.

Cyclinder -the drink packaging has clean line construction and easy to clean, disinfect and has smooth lines.- the shape of packaging is usually found in the market.

-the cost of packaging material is lower because it has small total surface.

Conclusion After doing research, answering questions, drawing graphs and some problem solving, I saw that the usage of statistics is important in daily life. It is not just widely used in markets but also in interpreting the condition of the

23

surrounding like the air or the water. Especially in conducting an air-pollution survey. In conclusion, statistics is a daily life necessities. Without it, surveys can’t be conducted, the stock market can’t be interpret and many more. So, we should be thankful of the people who contribute in the idea of statistics.

ReflectionWhile I conducting this project, a lot of information that I found. I

have learnt how statistics appear in our daily life.

Apart from that, this project encourages the student to work together and share their knowledge. It is also encourage student to gather information from the internet, improve thinking skills and promote effective mathematical communication.

Not only that, I had learned some moral values that I practice. This project had taught me to responsible on the works that are given to me to be completed. This project also had made me felt more confidence to do works and not to give easily when we could not find the solution for the question. I also learned to be more discipline on time, which I was given about 2 weeks to complete this project and pass up to my teacher just in time. I also enjoy doing this project I spend my time with friends to complete this project and it had bonded up our friendship deeply.

Last but not least, I proposed this project should be continue because it brings a lot of moral value to the student and also test the students understanding in Additional Mathematics.
