The mean SAT score in mathematics is 492. The founders of a nationwide SAT preparation course claim that graduates of the course score higher, on average, than the national mean. Suppose that the founders of the course want to carry out a hypothesis test to see if their claim has merit. State the null hypothesis H_0 and the alternative hypothesis H_1 that they would use. H_0: H_1:

null hypothesisthat will be used by the founders of the SAT preparation course would use by virtue of the description is; H_0; mean = 492 while thealternativehypothesis H_1; mean > 492.## What is the null hypothesis and alternative hypothesis?
