1.Listed below are the 35 members of the Metro Toledo Automobile Dealers Association. We would like to estimate the mean revenue from dealer service departments. The members are identified by numbering them 00 through 34. We want to select a random sample of five dealers. The random numbers are: 17, 78, 28, 34, 32, 37, 45, 61, 65, 82, 11 and 45. Which dealer ID numbers would be included in the sample? (Enter the numbers as they appear in the spaces below, not their names.) A sample is to consist of every eighth dealer. The number 1 is selected as the starting point. Which dealer ID numbers are included in the sample? Enter the ID numbers in the order they appear. 2.A population consists of the following five values: 11, 12, 16, 17, and 22. a.List all samples of size 3, and compute the mean of each sample.
