Expert Solution
Step 1

Hi, we can solve just one question (upto 3 subparts) per post. Since only question 2 is completely visible, we'll solve that for you.  Kindly repost complete information for other questions you'd like answered.

Step 2

Test statistic is the smaller of the sum of positive ranks and sum of negative ranks.

Here, Sum of positive ranks = 288

Sum of negative ranks = 200

Since sum of negative ranks is smaller of the two, the test statistic will be t= 200
