3) Franchise: Candy Store- Do you want to own your own candy store? With some interest in running your own business and a decent credit rating, you can probably get a bank loan on startup costs for franchises such as Candy Express, Fudge Company, Karmel Corn and Rocky Mountain Chocolate Factory. Startup costs (in thousands of dollars) for a random sample of candy stores are given below: 95 173 129 95 75 94 116 100 85 a) With a x= 106.9 and a SAMPLE STANDARD DEVIATION of s 29.4 (Hint: the population standard deviation (G) is NOT KNOWN), find a 90% confidence interval for the population average startup costs, µ, for candy store franchises.
