Attempts: Keep the Highest 76 6. Three different distributions There are 431f-service restaurants in Alaska. The mean number of seats per restaurant is 77.9. (Source Data based on the 2002 Economic Census from U.S. Census Bureau) Suppose that the true population mean = 77.9 and standard deviation - 20 are unknown to the lasa tourism board. They select a simple random sample of 50 full-service restaurants located within the state to estimate y. The mean number of seats per restaurant in the sample is M - 32.1, with a sample standard deviation of s. 186. The standard deviation of the distribution of sample means that is, the standard error, is (Notes Although and are unknown to the Alaska tourism board, they are known to you for the purposes of calculating these answers.) The standard or typical average difference between the mean number of seats in the 431 full service restaurants in Alaska (p = 77.9) and one randomly selected full-service restaurant in Alaska is The standard or typical average difference between the mean number of seats in the sample of 50 restaurants (M 82.1) and one randomly selected restaurant in that sample is The standard or typical average difference between the mean number of seats in the 431 full service restaurants in Alaska (w = 77.9 and the sample mean of any sample of size 50 is The score that locates the mean number of seats in the Alaska tounam board's sample (M - 32.1) in the distribution of sample means is Use the unit normal tables and accompanying figures to answer the
