T F 1. A p-value of .008 in hypothesis testing means there is only a .8% chance we could get such sample statistics from the population if the null hypothesis is as stated. Such an event is considered unlikely and we would reject the null hypothesis. T F 2.

When performing inference on population means we require that the data are normal and/or that the sample size is large (to use the Central Limit Theorem) so that the sample means have a sampling distribution that is at least approximately normal. The exact same statement (in bold) holds for performing inference on population variance(s) using the χ 2 or F-test. (a) True (b) False

When we did hypothesis testing for proportions in class, we were able to use a normal distribution in all cases, provided the sample size was large enough. Explain why we can always apply the Central Limit Theorem to a random variable X, if X ∼ Bern(p) and the sample size is sufficiently large.

Assume that the population variance is unknown. We test the hypothesis that Ho: µ=5 against the one-sided alternative H1: µ≠5 at a level of significance of 5% and with a sample size of n=30. We calculate a test statistic = -1.699. The p-value of this hypothesis test is approximately ? %. Write your answer in percent form. In other words, write 5% as 5.0.
