The following data are taken from an experiment in which the subjects were tested for motion sickness. The subjects were randomly assigned to either the control group which was given a placebo or the experimental group which was given the drug Astemizole and observed on an ocean voyage. The same subjects were then switched and those that had the placebo were now given the drug, and those that had the drug were now given a placebo and observed on a new ocean voyage taking the same course. The results are the number of head movements that the subjects could endure without becoming nauseous. Use α = 0.05 to test the claim that Astemizole is effective, i.e. it takes a larger number of head movements before the subject gets nauseous.
