Please answer the following. Take a * picture of your solution and box your answer. Then upload it for submission. 1. A magazine claims that the mean amount spent by a customer at Burger Stop is greater than the mean amount spent by a customer at Fry World. The results for samples ofcustomer transactions for the two fast food restaurants are shown at the right. At a = 0.0". can you support the magazine's claim? Assume the population variances are equal. 2. A pet association claims that the mean annual costs of food for dogs and cats are the same. The results for samples of the two types of pets are shown at the right. At a = 0.10. can you reject the pet association's claim? Assume the population variances are not equai. Sample Statistics for Amount Spent by Customer: ' its-gem l Fry'Wuld E1 = $5.46 E2 = $5.12 51 = $0.89 52 = 3039 n, = 22 n; = 30 Sample Statistics [or Annual Food Costs 31 = $239 :2 = $203 5' = $32 52 = 521 n. = 16 :12 = 13 3. To compare the braking distances for two types oftiresma safety engineer conducts 35 braking tests for each type. The mean braking distance for Type A is 42 feet. Assume the population standard deviation is 4.7 feet. The mean braking distance for Type B is 45 feet. Assume the population standard deviation is 4.3 feet. At a = 0.10, can the engineer support the Claim that the mean braking distances are different for the two types of res? .1, Add file
