Outcomes and the Type I and Type II Errors · Try It 4
Determine both Type I and Type II errors for the following scenario:
Assume a null hypothesis, H_0, that states the percentage of adults with jobs is at least 88%.
Identify the Type I and Type II errors from these four statements.
(a) Not to reject the null hypothesis that the percentage of adults who have jobs is at least 88% when that percentage is actually less than 88%
(b) Not to reject the null hypothesis that the percentage of adults who have jobs is at least 88% when the percentage is actually at least 88%.
(c) Reject the null hypothesis that the percentage of adults who have jobs is at least 88% when the percentage is actually at least 88%.
(d) Reject the null hypothesis that the percentage of adults who have jobs is at least 88% when that percentage is actually less than 88%.
