Question: A researcher is testing the effect of a new cold and flu medication on reaction time. A sample of n = 16 students is obtained and each student is given the normal dose of the medicine. Thirty minutes later, each student's reaction time is measured. The scores for the sample averaged M = 220 milliseconds with SS = 6000.

Assuming that reaction time for students in the regular population averages  = 200 milliseconds, are the data sufficient to conclude that the medication has a significant effect on reaction time?
