Bug Description

Shapiro-Wilk tests nomality for both groups separately instead of the normality of the residuals

Expected Behaviour

Shapiro-Wilk should test nomality for residuals only. All other t-tests and qq-plots get this right.

Steps to Reproduce

1. open any data set for independent samples t-Test from the library
2. do a shapiro-wilk test
