# Question

With reference to Example 12.5, suppose that we reject the null hypothesis if x ≤ 15 and accept it if x > 15. Calculate µ(θ) for the same values of θ as in the table on page 341 and plot the graph of the power function of this test criterion.

Example 12.5

With reference to Example 12.1, suppose that we had wanted to test the null hypothesis θ ≥ 0.90 against the alternative hypothesis θ < 0.90. Investigate the power function corresponding to the same test criterion as on page 334, where we accept the null hypothesis if x > 14 and reject it if x F 14. As before, x is the observed number of successes (recoveries) in n = 20 trials.
