I have the correct answers. Please provide me with a step by step on how to manually calculate the answers to each of the questions.

Use the following information to calculate your answers to questions 10 through 14.

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.

Individual	Score After the Program	Score 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

1. What is the sum of positive signed ranks (T⁺)?The correct answer is: 36.50

2. The mean Tis? The correct answer is: 22.50

3. The value of T is?The correct answer is: 8.44

4. At = 0.05, what can be concluded about the effectiveness of the training program?The correct answer is: Since p-value is greater than alpha, we can conclude that the training program was ineffective.

5. At = 0.2, what can be concluded about the effectiveness of the training program?The correct answer is: Reject H_o: the training program was effective.
