Question

Assume that a hypothesis test of the given claim will be conducted. Identify the type I or type ll error for the test. 26) A psychologist claims that more than 2.1% of adults suffer from extreme shyness. Identify the type II error for the test. [4 Marks] 26) A) Fail to reject the claim that the percentage of adults who suffer from extreme shyness is equal to 2.1% when that percentage is actually less than 2.1% B) Fail to reject the claim that the percentage of adults who suffer from extreme shyness is equal to 2.1% when that percentage is actually greater than 2.1%. C) Reject the claim that the percentage of adults who suffer from extreme shyness is equal to 2.1% when that percentage is actually greater than 2.1%. D) Reject the claim that the percentage of adults who suffer from extreme shyness is equal to 2.1% when that percentage is actually 2, 1% 27) Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclutuion about the null hypotheses(reject the null hypothesis of fail to reject the null hypothesis) The test statistic in a two-tailed test is z = 2.22 Marks] 17 2 A) 0.0132; reject the null hypothesis B) 0.0264; fail to reject the null hypothesis C) 0.0132; fail to reject the null hypothesis D) 0.0264; reject the null hypothesis

Explanation / Answer

27) given that z value is 2.22 and a two tailed test with los 0.05 =alfa

Then p value corresponding to the given information is

P = 0.0264

Since p value < 0.05 We reject the null hypothesis

Option d

0.0264 ; reject the null hypothesis
