level of significance -ANSWER The probability of making a Type I error when the null hypothesis is true as an equality the null hypothesis. -ANSWER In hypothesis testing, the tentative assumption about the population parameter is called: Which of the following describes a Type II Error? -ANSWER Accept H0 when H0 is false. Whenever the probability of making a Type II error has not been determined and controlled, only two conclusions are possible. We either reject H0 or: -ANSWER do not reject H0. Which of the following describes a Type I Error? -ANSWER Reject H0 when H0 is true. significance tests. -ANSWER Applications of hypothesis testing that only control for the Type I error are called: As the test statistic becomes larger, the p-value: -ANSWER becomes smaller. For a two-tailed test, the p-value is the probability of obtaining a value for the test statistic as: -ANSWER unlikely as that provided by the sample. For a lower tail test, the p-value is the probability of obtaining a value for the test statistic: -ANSWER at least as small as that provided by the sample. The p-value is a probability that measures the support (or lack of support) for the: -ANSWER null hypothesis. What is the probability of making a Type I error? -ANSWER a The p-value: -ANSWER must be a number between 0 and 1. Which of the following does not need to be known in order to compute the p-value? -ANSWER The level of significance For the case where σ is unknown, which statistic is used to estimate σ? -ANSWER s For the case where σ is unknown, the test statistic has a t distribution.
