Problem 8E

An article in the Journal of Testing and Evaluation (1988, Vol. 16, pp. 508–515) investigated the effects of cyclic loading frequency and environment conditions on fatigue crack growth at a constant 22 MPa stress for a particular material. The data follow. The response variable is fatigue crack growth rate.

(a) Is there indication that either factor affects crack growth rate? Is there any indication of interaction? Use α = 0.05.

(b) Analyze the residuals from this experiment.

(c) Repeat the analysis in part (a) using ln(y) as the response. Analyze the residuals from this new response variable and comment on the results.

Step-by-Step Solution:
Step 1 of 3

Aggression  Stereotype is that men are more aggressive: not true!  Response form: when they were looking at aggression in the 70’s they would watch kids aggressive behavior (hitting and kicking) on the playground and found that the boys were more aggressive and that is where the stereotype came from. However, while this may be true with children, it is not with adults  Intent to harm: trying to separate accidents with intent of harm with accidents  Teacher/Learner Paradigm: “Buss aggression machine”: have individuals primed to be aggressive or not. Bring individuals into lab and had them play games and messed them up and insulted them during the game to piss them off and make them aggressive. Found that frust
