For a study with a related-samples design and 30 participants in which each participant is measured twice (repeated measures),what is the critical value? Assume a two-tailed test with $\alpha$ = 0.05.
A)1.699
B)2.042
C)2.045
D)2.048

To find the critical value, we need to use the F-distribution table for related-samples design with alpha = 0.05 and 29 degrees of freedom (30 participants minus 1). The critical value is the value at which the null hypothesis would be rejected.

From the table, we can see that the critical value is 2.045. Therefore, the answer is C.
