Example 10.5.2 We have to test the claim of a publisher that µ, the averagenumber of misprints per page of a book is 1. If a randomly chosen page ofthat book contains more than two misprints then the null hypothesis µ = 1is rejected. What is the probability of type-I error? Find the power of thetest when the alternative hypothesis is u = 2. (e = 0.368)%3D

Question 36. We are interested in significant differences (level a = 0.05) between the expected values 41 and µ2 of two populations. Which of the following statements on statistical tests are correct? a) We will formulate the null hypothesis as 41 = 12. b) A t-test can always be applied in this situation. c) A p-value is the probability that the null hypothesis is correct, given the observed data. d) If we obtain a p-value of 0.04, we will reject (level a = 0.05) the null hypothesis.

Suppose we are interested in investigating the mean of a normally distributed population. As part of the investigation, we intend to draw a sample of 1400 observations from this population and carry out a test of the null hypothesis Ho : µ =450 against a two-sided alternative hypothesis. Suppose that in reality, the population mean is 450. On average, what will the p-value equal? (Give your numeric response to at least 3 decimal places.
