They have selected a class of 30 students to be taught according to this new method. At the end of the semester the average grade of these students was 78. Assume that the mean (µ) grade across all of the business analytics classes that do not utilize this new method is 72 with a standard deviation of 10.

What would be the proper set of hypotheses?

Using the p-value approach, what is p-value you would use?

Based on this test, would you reject the null hypothesis and or the alternative hypothesis?
