A researcher is using a repeated measures design to evaluate the effectiveness of a pain-relief patch designed for lower back pain. Prior to testing the patch, each of n = 5 patients rates the current level of back pain on a scale from 1 to 10. After wearing the patch for 90 minutes, a second pain rating is recorded. Please calculate the appropriate hypothesis test using all FOUR STEPS (hint: Use a two-tailed with an α = .05). Show all four steps below but you do not have to show your work or include symbols or equations in Blackboard because it is too much of a hassle.

The data are as follows:

• Mean difference (MD)= 11

• Sum of squares of the difference (SS)= 74

• n = 5

1a) A researcher conducts an independent-measures study to examine how the brain chemical serotonin is related to aggression. One sample of rats serves as a control group and receives a placebo that does not affect normal levels of serotonin. A second sample of rats, low serotonin group, receives a drug that lowers brain levels of serotonin. Then, the researcher tests the animals by recording the number of aggressive responses each of the rats display. See the data below. Is there...
