The file P02_10.xlsx contains midterm and final exam scores for 96 students in a corporate finance course. For this problem, assume that these 96 students represent a sample of the 175 students taking the course, and that these 175 students represent the relevant population.
a. Assuming the same instructor is teaching all four sections of this course and that the 96 students are the students in two of these sections, is it fair to say that the 96 students represent a random sample from the population? Does it matter?
b. Find the sample mean and the standard error of the sample mean, based on the 96 students in the file. Should the finite population correction be used? What is the standard error without it? What is the standard error with it?
