16 6 mance of four genetically different strains of mice, using eight mice per strain. Performance for the four strains were as follows: Strain Mean S 41 3.5 38 4.6 14 3.8 37 4.9 Using the .01 significance level, is there an overall difference in maze per- formance among the four strains? (a) Use the steps of hypothesis testing; (b) sketch the distributions involved; (c) figure the effect size for the study; and (d) explain your answer to part (a) to someone who is familiar with hypothesis
