List two variables that you could study the relationship between using a correlated groups t-test. For each variable, indicate if the variable is (1) the IV or DV, (2) nominal, ordinal, interval, or ratio, and (3) the values of each variable. Then briefly describe what makes it a within-subjects design.

HW#9-Chapter 18 (20pts for turned in on time) Paired t test is when two dependent groups are compared with each other, and to perform a paired t test, a Difference will be calculated first between each pair of the individuals of the two groups, and then a one-sample t test will be conducted on the Difference. (10pts)There is evidence that cytotoxic T lymphocytes (T cells) participate in controlling tumor growth and that they can be harnessed to use the body's...
For a correlated groups t test, the null hypothesis states that _____. H0: μ1 - μ2 = 0 H0: μ1 - μ2 > 0 Ha: μ1 - μ2 = 0 Ha: μ1 - μ2 = 0
The t test for correlated groups requires that o the sampling distribution of raw scores is normally distributed o the sampling distribution of means is normally is normally distributed the population raw scores are normally distributed O Nis greater than 30
