The histogram below shows the number of hours that students in a statistics class exercise each week. (a) ( (b) (c) ( 14 12 10 8 6 4 2 0 0.0 2.5 5.0 7.5 10.0 12.5 15.0 17.5 ) In which of the following ranges of values does the median lie: 0 - 2.5, 2.5 - 5, 5 - 7.5, or 7.5 -10? Is this distribution skewed to the right, skewed to the left, or symmetric? Do we expect the mean to be greater than, less than, or equal to the median?
