(1):

Explanation of Solution
Option (a):
Interest rate (i) is 18% and time period (n) is 33.
The
The future value factor to the present value is 244.545.
Option (b):
The future value factor to the present value (FP) through formula can be calculated as follows:
The future value factor to the present value is 235.5625.
(2):
Calculate annual growth rate.
(2):

Explanation of Solution
Option (a):
Interest rate (i) is 12% and time period (n) is 54.
The annual growth rate value (AG) through linear interpolate can be calculated as follows. The interest rate lies between (i1) 11% and (i2) 13%.
The annual growth factor value is 8.3356.
Option (b):
The annual growth factor value (AG) through formula can be calculated as follows:
The annual growth factor value is 8.2143.

- Test Preparation QUESTION 2 [20] 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) QUESTION 3 2 4 6 8 10 12 41 38 33 27 23 19 Derek investigates the relationship between the days (per year) absent from work (ABSENT) and the number of years taken for the worker to be promoted (PROMOTION). He interviewed a sample of 22 employees in Cape Town to obtain information on ABSENT (X) and PROMOTION (Y), and derived the following: ΣΧ ΣΥ 341 ΣΧΥ 176 ΣΧ 1187 1012 3.1 By using the OLS method, prove that the constant and slope parameters of the…arrow_forwardQUESTION 2 2.1 [30] Mariana, a researcher at the World Health Organisation (WHO), collects information on weekly study hours (HOURS) and blood pressure level when writing a test (BLOOD) from a sample of university students across the country, before running the regression BLOOD = f(STUDY). She collects data from 5 students as listed below: X (STUDY) 2 Y (BLOOD) 4 6 8 10 141 138 133 127 123 2.1.1 By using the OLS method and the information above derive the values for parameters B1 and B2. 2.1.2 Derive the RSS (sum of squares for the residuals). 2.1.3 Hence, calculate ô 2.2 2.3 (6) (3) Further, she replicates her study and collects data from 122 students from a rival university. She derives the residuals followed by computing skewness (S) equals -1.25 and kurtosis (K) equals 8.25 for the rival university data. Conduct the Jacque-Bera test of normality at a = 0.05.

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.
