Suppose a 99% CI was provided: (15.2, 16.4), does this means that 99% of students take between 15.2 and 16.4 credits per semester? What was the sample mean used? What was the maximum error of the CI?

Solutions

Expert Solution

From given confidence interval we can not say that 99% of students take between 15.2 and 16.4 credits per semester.

Sample mean from given confidence interval is 15.8

Maximum error of confidence interval is 0.6

Complete solution is given in attached image:
