Practical Data Analysis with JMP®

Application

Now that you have completed all of the activities in this chapter, use the concepts and techniques that you've learned to respond to these questions.

1. Scenario: You live in a community of 23,847 households. You want to select a simple random sample of 250 of these households from a printed list of addresses.

   1. Use JMP to generate a random list of 250 integers; report the first 10 and last 10 integers on the list.

   2. Suppose that, from prior figures, you estimate that 18% of these households (approximately 4,300) have no Internet service. Use what you've learned in this chapter to estimate the probability that a random sample of 250 households would contain only households with Internet service.

   3. Estimate the probability that an SRS of 250 ...
