25.Starbucks randomly asked two groups of people if they function better with coffee or an

electric shock in the morning. The people in the first group each had a cup of coffee in the

morning, and 643 out of the 702 said they were more productive than usual. The people in the

second group were electrocuted in the morning, and 469 out of 525 said they were more

productive than usual. Is there significant evidence to conclude that the proportion of

individuals who have a cup of coffee in the morning and feel more productive is more than the

individuals who are electrocuted? Use the a = .05 level of significance.
