o 0 oo a0 oo 13. (2 points) Where is a randomization distribution centered? The value of the sample statistic It depends on the sample The hypothesized value of the parameter in the null hypothesis You do not know where a randomization distribution will be centered 14. (2 points) Reallocating cases to treatment groups while keeping the response values the same, making true then bootstrapping, and randomly permuting/scrambling/shuffling one variable are all ways to create what? a. b. C. d Creating confidence intervals Making randomization distributions Confusing variables Making a conclusion in context 15. (2 points) Suppose you want to test the hypothesis and you have a 95% confidence interval for that is . Based on the interval, what decision to you make? b. C. d. Reject Fail to reject We can’t use an interval to test a hypothesis This hypothesis is not in the proper form 16. (2 points) Based on the previous question, what is your significance level with your decision? a. b c. d 1% 95% 5% 20% 17. (2 points) From the confidence interval for a population proportion, which of the following null hypothesized values of will lead to not rejecting the null hypothesis? 0.64 0.62 0.50 0.56 18. (2 points) Suppose the normal curve shown to the right is approximating a randomization distribution for a test of the form. Which of the following values of would provide the smallest amount of evidence against ? P oo 0 @ >
