2.1 Body Mass Index (BMI) is a summary measure of relative health. It is calculated by dividing an
individual's weight (in kilograms) by the square of their height (in meters).
A small sample was drawn from the population of UWC students to determine the effect of exercise
on BMI score. Given the following table, find the constant and slope parameters of the sample
regression function of BMI = f(Weekly exercise hours). Interpret the two estimated parameter
values.

After the reopening of borders with mainland China following the COVID-19 lockdown, residents living near the border now have the option to shop for food on either side. In Hong Kong, the cost of food is at its listed price, while across the border in mainland China, the price is only half that of Hong Kong's. A recent report indicates a decline in food sales in Hong Kong post-reopening. ** Diagrams need not be to scale; Focus on accurately representing the relevant concepts and relationships rather than the exact proportions. (a) Using a diagram, explain why Hong Kong's food sales might have dropped after the border reopening. Assume that consumers are indifferent between purchasing food in Hong Kong or mainland China, and therefore, their indifference curves have a slope of one like below.
