1)
k) chi-square test of independence is correct
as we have to test the independence of two categorical variables
2)
i) pearson correlation test
we have to see relation between two variables
3)
c) paired t-test as we have to compare the mean and sample remain same.
4)
l) McNemar test
The McNemar test is a non-parametric test for paired nominal data.
It's used when you are interested in finding a change in proportion for the paired data.
