7. The heights of a random sample of 50 college students showed a mean of 174.5 centimeters and a standard deviation of 6.9 centimeters. a. Construct a 98% confidence interval for the mean height of all college students. b. What can we assert with 98% confidence about the possible size of our error if we estimate the mean height of all college students to be 174.5 centimeters? c. Construct a 98% prediction interval. 7.
