For a projected one-tailed test, lower tail critical, at the .05 level of significance, construct two rough graphs. Each graph should show the sector in the true sampling distribution that produces a type II error and the sector that produces a correct decision. One graph should reflect the case when H0 really is false because the true population mean is slightly less than the hypothesized population mean, and the other graph should reflect the case when H0 really is false because the true population mean is appreciably less than the hypothesized population mean.
Answer to relevant QuestionsHow should a projected hypothesis test be modified if you’re particularly concerned about (a) The type I error? (b) The type II error? It’s tempting to claim that once a particular 95 percent confidence interval has been constructed, it includes the unknown population characteristic with a probability of .95. What is wrong with this claim? Review Question 2.16 on page 54 lists the GPAs for groups of 27 meditators and 27 non-meditators. (a) Given that the mean GPA equals 3.19 for the meditators and 2.90 for the non- meditators, and that s 2 p equals .20, ...The investigator mentioned in Review Question 14.14 wishes to conduct a more extensive test of the effect of alcohol consumption on the performance of automobile drivers, possibly to gain more information about the legal ...Each of the following (incomplete) ANOVA tables represents some experiment.
