The null hypothesis that will be used by the founders of the SAT preparation course would use by virtue of the description is; H_0; mean = 492 while the alternative hypothesis H_1; mean > 492.
<h3>What is the null hypothesis and alternative hypothesis?</h3>
Null and alternative hypotheses are statistical terms used in hypothesis testing of data. It therefore follows that the null hypothesis of such a test always predicts no effect or no relationship between variables, while the alternative hypothesis on the other hand states one's research prediction of an effect or relationship.
It therefore follows from the paragraph above that the alternative hypothesis is described by the statement that the mean score is greater than 492.
