# Question: Refer to the sample data given in Exercise 1 If

Refer to the sample data given in Exercise 1. If we want to test for equality of the three means, why donâ€™t we use three separate hypothesis tests for Âµ1 = Âµ2, Âµ1 = Âµ3 and Âµ2 = Âµ3?

Assume that we plan to use a 0.05 significance level to test the claim that the different size categories have the same mean chest deceleration in the standard crash test.
