Textbook Question
Chapter 15, Problem 33SE
The sign test is a very simple procedure for testing hypotheses about a population
We wish to test H0:
- a. Determine the P-value of the test when Y = 15. [Hint: Think of a “success” as a lifetime that exceeds 25.0. Then Y is the number of successes in the sample. What kind of a distribution does Y have when
- b. For the given data, should H0 be rejected at significance level .05?
[Note: The test statistic is the number of differences Xi − 25 that have positive signs, hence the name sign test.]
