# The test statistic for the HR manager's hypothesis test about the mean number of recorded participants is 13.86. The criticalvalue is -1.751. The rejection region is left-tailed. Conclude whether to reject or not reject Ho, and interpret the results.Select the correct answer below:OReject Ho. The test results are not statistically significant and at best, provide weak evidence against the nullhypothesis.Reject Ho. The data provide sufficient evidence to conclude that the alternative hypothesis is true.Do not reject Ho. The test results are not statistically significant and at best, provide weak evidence against theOOnull hypothesis.ODo not reject Ho. The data provide sufficient evidence to conclude that the alternative hypothesis is true.

Question
Step 1

Decision based on critical value:

For a left tailed test, if the test statistic is smaller than the critical value, then reject the null hypothesis, H0. Otherwise fail to reject H0.

If H0 is rejected, then it can be interpreted that “there is enough evidence to suggest that  H0 is false, that is, to support the claim made by the alternate hypothesis, Ha at level of significance α”.

Step 2

Identifying whether the null hypothesis is rejected or not:

Here, the test static for the HR manager’s hypothesis about the mean number of record participants is 13.86. The critical value is –1.751. The rejection region is left- tailed. But here, the test statistic is not smaller than the critical value. That is, test statistic (13.86) > c...
