Name: Jordan Witte Module 4 Homework Assignment 1. Determine whether the samples are independent or dependent. The effectiveness of a new headache medicine is tested by measuring the amount of time before the headache is cured for patients who use the medicine and another group of patients who use a placebo drug. Explain. Solution: The two samples are independent as the data being collected are unrelated. They are two different test groups comparing a medicine and a placebo drug effect. Instructor Comments: 2. Determine whether the samples are independent or dependent.

The data consist of before and after intensities for each patient. Explain. Solution: The two samples are dependent because the data collected are paired and related between the two groups. They are using the same medicine of the same people before and after.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
