Thirty-two people were chosen at random from among the employees of a large corporation. Their commute times (in hours) from home to work were recorded in the following table:

(A) Construct a frequency and relative frequency table using a class interval width of 0.2, starting at 0.15.

(B) Construct a histogram.

(C) What is the probability that a person chosen at random from the sample will have a commuting time of at least an hour? Of at most half an hour?

(D) Construct a histogram using a graphing calculator.
