Ms Ratchett's math class averaged poorly on a test, so she gave them a retest. If all 30 students in the class scored 10 points higher
on the retest, how would the MEAN of the retest scores differ from the MEAN of the scores on the first test?
The means would be the same.
The mean on the retest would be 3 points higher
The mean on the retest would be 10 points higher
The mean on the retest would be 13 points higher
