Students monitor surveys 1200 undergraduates from 100 colleges semiannually to understand trends among college students. recently, the students monitor reported that theaverage amount of time spent per week on the internet was 19.0 hrs. assume that the standard deviation is 5.5 hours.
(a) give the mean and standard deviation in minutes.
(b)calculate the 95% confidence intervial in minutes from your answer
(c)explain how you could have directly calculated this intervial from the 95% that you calculated in the previous exercise
