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.

IndividualScore After

the ProgramScore Before

the Program 1 57 59 2 62 57 3 60 60 4 63 66 5 69 68 6 63 59 7 74 72 8 56 52 9 64 58 10 64 63

a. 8.50

b. 8.44

c. 71.25

d. 14.52

e. 22.50

Question text

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.

e. The study is inconclusive.

Question text

At α = 0.2, what can be concluded about the effectiveness of the training program?

Select one:

a. Reject H_{o}: the training program was ineffective.

b. The study is inconclusive.

c. Do not reject H_{o}: the training program was ineffective.

d. Reject H_{o}: the training program was effective.

e. Do not reject H_{o}: the training program was effective.

Thanks in advance
