A study measured how fast subjects could repeated push a button when under the effects of the caffeine in Mountain Dew soda. Subjects were asked to push a button as many times as possible in two minutes after consuming the soda. During another test session they were asked to push the button after drinking a placebo. The subjects did not know which treatment they were administered each day and the order of the treatments was randomly assigned. The data, given in presses per two minutes for each treatment is on the right. Is there evidence to determine whether or not the caffeine in Mountain Dew results in a higher rate of beats, on average, per two-minute period? Perform a hypothesis test at the 0.10 level of significance and state your conclusion.
