| Question | Ho | Ha | Reject Ho When | Test Statistic | Decision | Summary |
| #1 | p ≥ 0.25 | p < 0.25 | z < -1.645 | -3.380295845 | Do not Reject Ho | There is not sufficient statistical evidence to show the proportion of currently 0.25 is doing physical acttivity everyday. |
| #2 | p ≤ 0.30 | p > 0.30 | z > 1.645 | -3.23332646 | Do not Reject Ho | There is not sufficient statistical evidence to show the proportion of 0.25 physical activity can improve stress. |
| #3 | p = 0.45 | p ≠ 0.45 | z < -1.96 or z > 1.96 | -1.5 | Do not Reject Ho | There is not sufficient statistical evidence to show the proportion of 0.45 compiled a physical activity plan. |
| #4 | p ≥ 0.32 | p < 0.32 | z < -1.645 | -8.145870119 | Reject Ho | There is not sufficient statistical evidence to show the proportion of 0.32 physical activity helped improve mental health condition. |
| #5 | μ = 2.79 | μ ≠ 2.79 | z < -1.96 or z > 1.96 | -131.9434102 | Reject Ho | There is sufficient statistical evidence to show the mean of number of days for exercise is less than 2.79 |
