You can’t assume normality, so use an appropriate nonparametric method to

Test the claim that each group read the same number of books. Test using a

significance level of 10%. Draw appropriate conclusions.

(b) You are curious what the result would be if you used a parametric technique,

so please re-do the analysis using the appropriate two sample t-test. Comment on

the result.
