Question
K Thirty-two people were chosen at random from employees of a large company. Their commute times (in hours) were recorded in a table (shown on the right). Construct a frequency table using a class interval width of 0.2 starting at 0 15. (Type integers or simplified fractions.) Class Interval Frequency Relative Frequency. 0.15-0.35 0.35 -0.55 0.55-0.75 0.75 -0.95 0.95-1.15 1.15-1.35 1.35-1.55 Which histogram is representative of the above data?
