Randomly selected participants in a health program take a survey about their habits before and after going through the program. The program developer wants to determine if there is a significant increase in the amount (hours per week) of exercise after the program. Some of the results of the analysis follow:

Hypothesis test results:
_D = ₁ - ₂ : Mean of the difference between after and before
H₀ : _D = 0
H_A : _D > 0

Select the appropriate interpretation of the results.

Using a 0.05 level of signficance, there is not sufficient evidence to conclude that the mean amount of exercise will significantly increase after participating in the health program.

Using a 0.05 level of signficance, there is sufficient evidence to conclude that the mean amount of exercise will significantly decrease after participating in the health program.

Using a 0.05 level of signficance, there is sufficient evidence to conclude that the mean amount of exercise will significantly increase after participating in the health program.

The mean increase in the amount of exercises for all who will participate in this health program will be 0.5 hour per week.

Solution

to = 2.3717
P-Value:Right Tail -Ha : ( P != 2.3717 ) = 0.0209
Hence Value of P0.05 > 0.0209,Here we Reject Ho

Using a 0.05 level of signficance, there is sufficient evidence to conclude that the mean amount of exercise will significantly increase after participating in the health program.
