A large airline company called Skyology Inc. monitors customer satisfaction by asking customers to rate their experience as a 1, 2, 3, 4, or 5, where a rating of 1 means "very poor" and 5 means "very good". The customers' ratings have a population mean of u = 4.14, with a population standard deviation of o = 1.41. Suppose that we will take a random sample of n = 7 customers' ratings. Let x represent the sample mean of the 7 customers' ratings. Consider the sampling distribution of the sample mean x. Complete the following. Do not round any intermediate computations. Write your answers with two decimal places, rounding if needed. (a) Find u- (the mean of the sampling distribution of the sample mean). X 2 (b) Find o- (the standard deviation of the sampling distribution of the sample mean). X 5
