Sam feels that students score better on math tests that
take place on Fridays. The school provides Sam with the school
math test average, but they cannot separate them by date
taken. The school is too large for him to ask every student,
so he randomly selects a sample of willing students’ test scores
after the next Friday’s math test. He uses the method of
hypothesis testing to compare the Friday scores against the true
average of all scores. Frame the correct set of hypotheses for
his research. Decide where the rejection region will
lie.
