Is there a linear correlation between chocolate consumption and the rate of Nobel Laureates? Run a hypothesis test to test the claim that there is a linear correlation. If there is a correlation between chocolate consumption and the rate of Nobel Laureates, can we describe it with an equation so that we can predict the rate of Nobel Laureates if given the rate of chocolate consumption? In other words, what is the equation of the regression line? What would you predict is the rate of Nobel Laureates in a country, which consumes 9.1 kg of chocolate per capita?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
If you want to win a Nobel Prize, should you study subjects like physics, chemistry, and economics, or should you just eat more chocolate? The table below lists chocolate consumption (kg per capita) and the numbers of Nobel Laureates (per 10 million people) for each of 23 different countries. See Data Set 16 “Nobel Laureates and Chocolate” in Appendix B, where the countries are identified.
