entering class from previous years but their mean SAT score is lower than previous years.He took a
sample of 20 of this year's entering students and found that their mean SAT score is 1,501 with a
standard deviation of 53.The university's record indicates that the mean SAT score for entering
students from previous years is 1,520.He wants to find out if his claim is supported by the evidence
at a 5% level of significance.

evidence to show that the mean SAT score of the entering class this year is lower than previous
years with no more than a 5% probability of incorrectly rejecting the true null hypothesis.
