Question

PLEASE HELP FAST!! IT IS URGENT!! Some stores print multiple coupons and advertisements on their receipts, making the receipts unusually long. A curious shopper makes the same purchase at a random sample of 10 stores and measures the length of each receipt (n inches). Here are the results: 8.25, 7.5, 5, 9.5, 12, 5.5, 9, 14, 11.5, 18 Are the conditions for cons tructing at confidence interval met?

O No, the random condition is not met.
O No, the 10% condition is not net.
O No, the Normal/large sanple condition is not met.
O Yes, the conditions for inference are met.​

Answer 1

No, the Normal/large sample condition is not met. A confidence interval assumes that the underlying population follows a normal distribution and that the sample size should be at least 30. Since the sample size in this case is only 10, the Normal/Large Sample condition is not met and the conditions for constructing a confidence interval are not met.
