For Q1 to Q4 You are hired as a marketing executive in a leading beverage company. Your supervisor wants you to conduct a study on average expenditure on beverage by university students in Dhaka every week. One of your colleagues collected the data using simple random sampling method from two universities: BRAC: 100, 120, 150, 90, 70, 110, 105, 120, 95, 70, 145, 110, 150, 135, 125, 120, 130, 132, 115, 107, 102 NSU: 90, 157, 124, 143, 98, 105, 109, 145, 131, 156, 168, 134, 128, 118, 120, 111, 125, 150, 89, 152, 101

Q1: Input the data in SPSS and conduct a Five Number Summary

Q2: You colleague claims that the real average expenditure on beverage by university students in Dhaka every week is at least BDT 100. Consider only the dataset of BRAC only. Which kind of hypothesis test would you perform to check this? Do the dataset meets all the assumption/requirement of this test? How would you check?

Q3: You colleague claims that the real average expenditure on beverage by university students in Dhaka every week is at least BDT 100. Consider only the dataset of BRAC only. At At 5% significance level, perform the appropriate hypothesis test to check if that is plausible. Assume all the requirements of the test are met.

Q4: You manager claims that the real average expenditure on beverage by university students of NSU is greater than that of BRAC. Which kind of hypothesis test would you perform to check this? What are the assumptions/requirements of conducting this test? At 5% significance level, perform the appropriate hypothesis test to check.
