1. In general terms, what is a hypothesis test? a. A descriptive technique that allows researchers to describe a sample b. A descriptive technique that allows researchers to describe a population c. An inferential technique that uses the data from a sample to draw inferences about a population d. An inferential technique that uses information about a population to make predictions about a sample 2. A sample is selected from a population with a mean of u = 60 and a treatment is administered to the individuals in the sample. If a hypothesis test is used to evaluate the treatment effect, then what is the correct statement of the null hypothesis? a. u = 60 b. M + 60 C. M = 60 d. M # 60 3. Which of the following accurately describes the critical region for a hypothesis test? a. Outcomes that have a very low probability if the null hypothesis is true b. Outcomes that have a high probability if the null hypothesis is true c. Outcomes that have a very low probability whether or not the null hypothesis is true d. Outcomes that have a high probability whether or not the null hypothesis is true 4. A sample of n = 25 individuals is selected from a population with u = 80 and a treatment is administered to the sample. Which of the following is the most likely outcome if the treatment has a large effect? a. The sample mean should be very different from 80 and should lead you to reject the null hypothesis. b. The sample mean should be very different from 80 and should lead you 10 fail to reject the null hypothesis. c. The sample mean should be close to 80 and should lead you to reject the null hypothesis. d. The sample mean should be close to 80 and should lead you to fail to rejed the null hypothesis
