In a study of animal behaviour, statistical analyses were presented for eight different response variables using a significance level of 0.05. Assuming that all eight variables adhere to the null hypothesis and distribution, and that the P values for each of the eight tests are uncorrected, what is the probability of committing at least one Type I error?

A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOs) of major corporations. He believes that the mean systolic blood pressure, μ , of CEOs of major corporations is more than 136 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test and measures the systolic blood pressures of a random sample of 75 CEOs of major corporations. Suppose that the population of systolic...

Part 1: Information: A hypothesis of clinical interest was that vitamin C prevents the common cold. A study is organized to test this hypothesis using 20 participants. In the study, 10 were randomly allocated to receive vitamin C capsules and 10 were randomly allocated to receive placebo capsules. The number of colds over a 12-month period for each participant is recorded. The samples were randomly selected, and the populations are approximately normally distributed. Population variances are unknown but assumed to...
