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.

Question 1) A group of reviewers tested the quality of a product. The evaluation was to grade the quality of product on a 0-to-100-point scale. The results follow. Construct a stem and leaf diagram for these data and comment on any important features that you notice. Compute the sample mean, the sample standard deviation, and the sample median. A product rated above 90 is considered as best quality product. What proportion of the reviewers considered this particular product as best...
