Parents who think that mathematics education is very important are considering sending their children into two private high schools. The administration of the first school claims that its graduates take more mathematics classes on average. The administration of each school provided the parents with information on recent graduates. Students in a random sample of 28 graduates of the first high school took an average of of 4 mathematics classes with the standard deviation of 1. Students in a with a random sample of 35 graduates of the second high school took an average of 3.5 mathematics classes with the standard deviation of 1 1. Calculate 95% confidence intervals for the difference between the mean mathematics classes take by graduates of each high school. Let 1=First High School and 2= Second High School. In two decimal places
