Quizplus · Accepted Answer

The HR manager should review the confidence intervals across each of the twenty sites as this will give an indication of the strength and accuracy of the results. This will allow the HR manager to compare and contrast the findings across the various sites and determine whether there is an overall effect of gym opening hours on employee usage. Reviewing the null hypothesis, outliers, and levels of missing data may also be useful, but they are not as directly relevant to the differences in p-values across the sites.
