A researcher wanted to know the effect of a certain drug on the stamina of his subjects (10 young adults). Without the influence of the said drug, the 10 subjects were asked to make the maximum number of "push-ups". The following day, the same activity was repeated after the 10 subjects have taken the said drug and the results are shown in the following table:

1	5	4
2	11	8
3	17	12
4	15	10
5	10	7
6	12	10
7	9	6
8	6	5
9	13	8
10	7	5

Using the table on critical value of t, the value of t is 2.262 for significance at the 5% and 3.25 at the 1% level. Formulate the working hypothesis (Ha). Compute for t. Interpret your answer and make decision.
