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 percent.
Identify the Type I and Type II errors from these four possible choices.
(a) Not to reject the null hypothesis that the percentage of adults who have jobs is at least 88 percent when that percentage is actually less than 88 percent
(b) Not to reject the null hypothesis that the percentage of adults who have jobs is at least 88 percent when the percentage is actually at least 88 percent
(c) Reject the null hypothesis that the percentage of adults who have jobs is at least 88 percent when the percentage is actually at least 88 percent
(d) Reject the null hypothesis that the percentage of adults who have jobs is at least 88 percent when that percentage is actually less than 88 percent
