While the following simple random samples of Statistics test scores both come from populations that are normally distributed, we do not know the standard deviation of the populations. The first simple random sample is drawn from the scores on Exam 1 for an on-line Statistics class and the second simple random sample is drawn from the scores on the exact same Exam 1 for an on-land (traditional) Statistics class. Using the null hypothesis that there is no difference in the...

Student stress at final exam time comes partly from the
uncertainty of grades and the consequences of those grades. Can
knowledge of a midterm grade be used to predict a final exam grade?
A random sample of 200 BCOM students from recent years was taken
and their percentage grades on assignments, midterm exam, and final
exam were recorded. Let’s examine the ability of midterm and
assignment grades to predict final exam grades.
