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.
