Step-by-step explanation:

The interpretation of 95% confidence interval for population mean is that "A person can be 95% sure that the true population mean lies in it."

Given : The admissions director from Big City University found that (107.8, 116.2) is a 95% confidence interval for the mean IQ score of all freshmen.

i.e. There is a 95% probability (chance) that the interval from 107.8 to 116.2 contains μ.

Hence, the explanation is absolutely "correct" .
