Question

Suppose that Sarah is an analyst for family-style dining restaurant industry. When she was in college, one of her professors had claimed that the number of tables attended by a single server in a six-hour shift had a mean of 23 and a standard deviation of 6.0 tables per shift. She decides to conduct a one-sample z-test to see if the mean number of tables attended by a server in a six-hour shift is different from 23. In order to simplify her test, she assumes that her professor's standard deviation of 6.0 is valid. She collects data from a simple random sample of 105 servers at family-style dining restaurants. The results are summarized below. Test of = 23 vs. 1 23 The assumed standard deviation = 6.0 n Mean SE man z 105 212 586 -3.074 Using the software your professor requires, determine the p-value for this test. Give your answer as a decimal, precise to at least four decimal places. p = 0.0022
