Question
Chapter 20, Problem 1QP
To determine
Explain the significance of judging theories based on prediction rather than the way its sounds.
Expert Solution & Answer
Explanation of Solution
Predictions are a stepping stone of believing or not believing a theory because sometimes people want to believe some theories over others, as the theory seems to confirm what people already believe. In real life, before 1960s, people had no idea about wireless mobile phones until its invention. Therefore, people believed that the landline mobile phones is the final invention. However, a scientist predicts with the evidence of technological changes that people will use wireless mobile phones in the future. Since people accept theory because the evidence of the prediction seems to confirm the beliefs of the individuals. Therefore, prediction has more importance than a theory sounds good to people.

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.
X (Weekly exercise hours) Y (Body-Mass index)

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. Additionally, consider that there are no transport costs and the daily food budget for consumers is identical whether they shop in Hong Kong or mainland China.
