Before ___After
10 ___30
25 __13
8___ 28
11___ 35
19____ 5
7 _____17
5_____ 9
30____ 6
15____ 10
6 _____12

there are two different columns separated but the underscore and before is one group and after is the other group .

1.)A number of catfish were tagged and their feeding behavior was observed in a large river system. Half of the catfish tagged were located upstream above a bridge and the other half of the sample was located downstream. The data represents the number of insects eaten per day by a tagged catfish. The researcher wishes to know whether the mean number of insects eaten per day differs between tagged catfish upstream and downstream of the bridge. What is the most appropriate test to answer this question?

2.)Use the test from your answer in Question 7 to determine whether the feeding behaviors of catfish are different above and below the bridge. Use the dataset for Question 7 in the Excel file to answer this. What is the p value for test that you did? Don't forget to think about test assumptions! Answer format = 0.999

Please answer these questions using the data about. Thanks in advance
