Refer to the data of Exercise 8.37. To illustrate the effect that an extreme value can have on conclusions from an analysis of variance, suppose that the weight gained by the fifth turkey in the level 2, additive B group was 15.8 rather than 9.8.
In exercise

a. What effect does this have on the assumptions for an analysis of variance?
b. With 9.8 replaced by 15.8, if someone unknowingly ran an analysis of variance, what conclusions would he or she draw?
