H0: no increase in standard deviation Ha: standard deviation increases (b) Determine the p-value for the claim that the pesticide increases standard deviation of beetle lifespan. chi-sq = 18.03, p-value ~= 0.08 (estimate) (c) Using a level of significance of α=0.10, state your conclusion on the effe ...

... So far we have been considering examples where the outcomes form a finite or countably infinite set. In many situations it is more natural to model a situation where the outcomes could be any real number or vectors of real numbers. In these situations we usually model probabilities by means of integ ...

... I vs. Type II error: when we make a decision based on a significance test (reject vs. fail to reject), we hope our decision is correct, but it may in fact be wrong (we really have no way of knowingif we did, we wouldn’t have done the test in the first place). Sometimes we get a rare freak sample a ...
