Let X equal to the grade of a student in a stat course. Suppose that X is N(u, 100). Using the traditional method of teaching, the average student grade was u=60.
We want to test if the student´s grades in this course has increased due to a new teaching method. In order to test Ho: u=60 vs H1: u>60 we will use a random sample of n= 36 students. If x? = 63.5 is the avaerage grade of this sample, find the p-value.
