I need help on these 4 stats questions:

Section 3 Questions 9,10, 11 and 12 are based on the following set-up. Question 8 provides the random input values for digits indicated as A,B,C ,D, E and F in what follows. Solar energy panels are built along highways to generate electricity. The researchers claim that the solar energy generation works better along north south oriented highways as compared to east-west oriented highways and they are going to use the Wilcoxon signed rank test to test this claim. 5 months were selected randomly, and for each month the amount of energy (in kilowatts hours) supplied by the two types of highways was determined. The results are given below: Month North-South February A658 8921 April 7930 C317 July 5274 5120 September 7150 B148 October D608 8936 Question 9 (Mandatory) (2 points) What is the rank of the difference (East/West-North/South) for the month of July? Question 10 (Mandatory) (2 points) What is T+, the rank sum of positive differences? Question 11 (Mandatory) (2 points) What is $T$, the rank sum of negative differences? Question 12 (Mandatory) (2 points) What's the p-value of the Wilcoxon signed rank test
