Grand Sun Buffet is a large restaurant chain. After paying for a meal at Grand Sun Buffet, customers are asked to rate the quality of the food as a 1, 2, 3, 4, or 5, where a rating of 1 means "not good" and 5 means "excellent". The customers' ratings have a 圖 population mean of µ=4.80, with a standard deviation of o=1.47. Suppose that we will take a random sample of n= 10 customers' 00 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). ーテ (b) Find o- (the standard deviation of the sampling distribution of the sample mean).
