  What will be an ideal response?

Question 2

A researcher interested in determining the average monthly expenditures of college students on DVDs finds that for a sample of 25 students, the mean expenditure was 24.40, and the median expenditure was 21.76.
 
  Specify the shape of the histogram for this data. Does this shape make sense? Why?

Answer to Question 1

Event A: Student enjoyed class
Event B: Class taught by professors with good evaluations
P(B) = 0.84
P(A  B) = P(A  B) / P(B) = 0.609/0.84 = 0.725

Answer to Question 2

The distribution is skewed to the right, implying that there are a few students (outliers) who spend a lot of money on DVDs, raising the average above the typical or median student.
