Chapter 8, Problem 2E

The following is a list of 29 hospitals in the Cincinnati, Ohio, and Northern Kentucky region. Each hospital is assigned a number, 00 through 28. The hospitals are classified by type, either a general medical/surgical hospital (M/S) or a specialty hospital (S). We are interested in estimating the average number of full- and part-time nurses employed in the area hospitals.

1. a. A sample of five hospitals is to be randomly selected. The random numbers are 09, 16, 00, 49, 54, 12, and 04. Which hospitals are included in the sample?
2. b. Use a table of random numbers to develop your own sample of five hospitals.
3. c. Using systematic random sampling, every fifth location is selected starting with the second hospital in the list. Which hospitals will be included in the sample?
4. d. Using stratified random sampling, select five hospitals. Four should be medical and surgical hospitals and one should be a specialty hospital. Select an appropriate sample.
