Consider the following histogram of the data. A histogram has a horizontal axis labeled "Time (in months)" with values from 0.5 to 60.5 and a vertical axis labeled "Frequency" with values from 0 to 15. The histogram has 5 bars of equal width. Each bar is associated with an interval and an approximate value as listed below. 0.5 to 12.5: 5 12.5 to
