CIRCLE ALL CORRECT ANSWERS 6. You are conducting a one-sample t-test. Which of the following will help you reject the null hypothesis (hint: use formula below)? (Select all that apply) a) larger sample size b) smaller sample size M- u c) more degrees of freedom fewer degrees of freedom t = e) larger estimated standard error of the mean S f) smaller estimated standard error of the mean g) bigger difference between sample and population mean Vn h) smaller difference between sample and population mean i) bigger sample standard deviation smaller sample standard deviation k ) bigger population standard deviation smaller population standard deviation 7. A scientist wants to know if people exposed to radiation turn into superheroes. He plans to collect 100 individuals and have them bitten by either normal or radioactive spiders. He randomly assigns half of the participants to be bitten by normal spiders and the other half to be bitten by radioactive spiders. Then, he records the number of superpowers they each develop. Which of following is true of this proposed study? a) it is a correlational design b) it is a quasi-experiment it is a true experiment it is between subjects it is within subjects f ) it can be analyzed with an independent samples t-test g) it can be analyzed with a paired samples t-test h) it can be analyzed with a z-test PART 3: FILL IN THE BLANK (6 POINTS) 1. The t-test is used to analyze data with one within-subjects independent variable with (enter a number) levels, whereas the t-test is used to analyze data with no independent variable. 2. We must conduct a one-sample t-test instead of a z-test when we do not know the (be specific). 3. In the independent samples t-tests, we use variance in order to put proportional weight on the variance of each sample. 4. The t-distribution is actually a population/family of distributions that changes shape and critical values depending on the
