is this the right answer ? new problem

A repeated-measures t test was conducted to determine the efficacy of a new public health school program among 10^th grade students on the number of minutes they exercise per week. Based on measures taken before and after the program/after a month. The results indicate a significant increase on number of minutes the children exercise per week after treatment. (M=58.5, SD=11.1) as compared to before (M=46.3, SD=6.9). t (9)= -5.2, p = <.001, two tail

The scores are illustrated in Figure 1. Therefore, I reject the null hypothesis the p <.001 is significant. There is difference in the minute's children exercise after and before the public health program.

t(9) = -5.2 p = < .001 (two tailed)
