QUESTION 2 Previously, an organization reported that teenagers spent 4.5 hours per week, on average, on the phone. The organization thinks that, currently, the mean is higher. Fifteen randomly chosen teenagers were asked how many hours per week they spend on the phone. The sample mean was 4.75 hours with a sample standard deviation of 2 hours. Assume that hours per week they spend on the phone are normally distributed. At a significance level of 5%, test the claim of...
