There are 559 full-service restaurants in Delaware. The mean number of seats per restaurant is 99.2. [Source: Data based on the 2002 Economic Census from the US Census Bureau.] Suppose that the true population mean µ = 99.2 and standard deviation σ = 20 are unknown to the Delaware tourism board. They select a simple random sample of 50 full-service restaurants located within the state to estimate µ. The mean number of seats per restaurant in the sample is M = 103.4, with a sample standard deviation of s = 18.2.
