The starting salaries (in thousands of dollars) of 20 graduates, chosen at random from the graduating class of an urban university, were determined and recorded in the following table:

(A) Construct a frequency and relative frequency table using a class interval width of 4 starting at 30.5.

(B) Construct a histogram.

(C) What is the probability that a graduate chosen from the sample will have a starting salary above $42,500? Below $38,500?

(D) Construct a histogram using a graphing calculator.
