For this problem all manual computations/arithmetic must be carried to at least three decimals. The manager of the Inlet Square Mall wants to estimate the mean amount spent per shopping visit by customers. A sample of 20 customers reveals the following amount spent. 45.16 39.18 43.76 34.86 57.83 48.35 20.88 38.86 49,86 49.74 43.59 48.82 42.94 58.69 44.17 59.46 48.35 49.68 53.74 42.08 Final Problem 1B data.xlsx Assuming normality, what is the 90% confidence interval estimate for the. average amount spent per shopping visit by customers? Round your answer to the nearest integer The lower confidence interval limit (LL) = The upper confidence interval limit (UL) = Based on the sample data and with 90% confidence, would it be reasonable to conclude that the average amount spent by the customers visiting the mall is $52. Enter "Y" if it is reasonable and enter "N" if it is not.
