When estimating the range of the population data, we are interested in the lowest and highest values between which the data exist. Consider histogram (i), which has a sample size of 30. (i) Sample of size 30A histogram has a horizontal axis with values from 27.25 to 32.25 and a vertical axis labeled "Frequency" with values from 0 to 10. The histogram has 10 bars. Each bar is associated with a midpoint and a value as listed below. 27.5: 1 28: 0 28.5: 2 29: 4 29.5: 3 30: 9 30.5: 6 31: 3 31.5: 1 32: 1 Notice that the midpoint labels of the bars are present on every other bar. This means that the bars in-between two consecutive values are understood to have a midpoint value halfway between the values marking the neighboring bars. For example, the bar between the midpoint labels 28 and 29 is 28.5. In this histogram, the first midpoint label is at 28 and the final midpoint label is at 32. So, the lowest value, represented by the bar to the left of the 28, is . There are no bars after 32, so the highest value is
