Hi,

Can someone please check my answer for the question below:

Test scores of 10 individuals before and after a training program are shown below. Note: despite the sample size, assume that the sampling distribution of T+ can still be approximated by a normal distribution.

At α = 0.05, what can be concluded about the effectiveness of the training program?

Select one:
a. Since p-value is greater than alpha, we can conclude that the training program was somewhat effective.
b. Since p-value is less than alpha, we can conclude that the training program was extremely effective.
c. Since p-value is less than alpha, we can conclude that the training program was ineffective.
d. Since p-value is greater than alpha, we can conclude that the training program was ineffective.
