Match the following scenarios with an appropriate R analysis.

You are testing three different diets. 50 people are randomly allocated to each diet and their change in weight is recorded.

Question 6 options:

Useaov

Useoneway.testwithvar.equal = FALSE

Usekruskal.test

1.You are confident that weight loss is normally distributed but when you run the Bartlett test you get a p-value less than 0.05.

2.Weight loss within each diet has a very skewed distribution

3.Weight loss within each diet appears to be normally distributed and each sub-group has approximately equal variance.
