Question 3. Suppose that for table servers at a large restaurant chain, their tips average $9.60 per table, with a standard deviation of $5.40.
a. You question a sample of 20 table servers at the chain's restaurants in this region about their tips from the first customers on their most recent shift. Describe the sampling distribution for the sample mean, for samples of size 20, of the mean tip amount for the severs. You should include a picture that approximates the sampling distribution, and label at least five tick marks in that drawing. Round to the nearest penny.
b. You find that, in your sample, the mean tip for the servers was $7.08. Assuming the mean and standard deviation provided, is this sample mean unusual? Justify your answer with a z-score.
