29 What is the pvalue for the following hypothesis test for

29. What is the p-value for- the following hypothesis test for a population proportion? A right-tailed test with test statistic z = 1.15. A) 09332 B) 1-0.9332 C) 0.8749 D) 1-0.8749 E) 2(1-0.8749) 30. A random sample of 20 yields a mean of 32.4. We wish to test the two-sided hypothesis that the mean was drawn from a population with a mean of 35. You are given that the appropriate standard error based on the sample size is 1.28. If the test statistic is -2.03, find the p-value. A) 0.065

Solution

9)
P-Value: Right Tail - Ha : ( P > -1.15 ) = 1 - 0.8749 = 0.1251

D) 1 - 0.8749
10)
P-Value : Two Tailed ( double the one tail )Ha : ( P != -2.03 ) = 0.0424

It lies in B) 2 * 0.015 < p-value < 2 * 0.030
