c) A human resource analyst wants to know if the applicants this year score, on average, higher on their placement exam than the $52.5$ points the candidates averaged last year. She samples 50 recent tests and finds the average to be $54.1$ points. She fails to reject the null hypothesis that the mean is $52.5$ points. At the end of the year, they find that the candidates this year had a mean of $55.3$ points.

Solution

A Type II error occurs when a null hypothesis is not rejected despite the fact that it is wrong.
