4. A researcher examined whether an over-the-counter cold medication has an effect on mental alertness. A sample of n = 16 participants is obtained, and each person is given a standard dos of the medication one hour before being tested on a driving simulation task. For the general population, scores on the simulation task are normally distributed with u = 60 ando = 8. The individuals in the sample had an average score of M = 56. Use a two-tailed test with a = .05.
