Textbook Question
Chapter 10.3, Problem 30E
Reconsider Example 10.8 involving an investigation of the effects of different heat treatments on the yield point of steel ingots.
- a) If J = 8 and a = 1, what is β for a level .05 F test
when μ1 = μ2, μ3 = μ1−1 and μ4 = μ1+1
- b) For the alternative of part (a), what value of J is necessary to obtain β = .05?
- c) If there are I = 5 heat treatments. J = 10. and σ = 1, what is p for the level .05 F test when four of the μi s are equal and the fifth differs by 1 from the other four?
