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=4.70, with a population standard deviation of o=1.75. Suppose that we will take a random sample of n = 10 customers' ratings. Let x represent the sample mean of the 10 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 - = 0 X 0--0 = X (b) Find o- (the standard deviation of the sampling distribution of the sample mean). X X
