The following histograms represent the estimates given by 12 eleven-year old boys and 9 eleven-year old girls of how much they would be expected to pay in a corner shop for a particular chocolate bar. Two graphs, one above the other, each consisting of a horizontal axis labelled 'Estimated price in pence' with a scale from 20 to 100 marked at intervals of 20. The upper histogram is labelled 'Boys' estimates of chocolate bar price' and has a vertical axis labelled 'frequency' with a scale from zero to 4 marked at intervals of 1 and has six vertical bars, each of width 5, with the first starting at 40. From left to right the heights of the bars are 2, 4, 3, 1, 1, 1 respectively. The lower histogram is labelled 'Girls' estimates of chocolate bar price' and has a vertical axis labelled 'frequency' with a scale from zero to 3 marked at intervals of 1 and has six vertical bars, each of width 5, with the first starting at 10. The height of the first bar is 1. There is then a gap, and the second bar starts at 25 and has height 1. There is then a gap, and the third bar starts at 35. From left to right the heights of the next three bars are 2, 3, 1 respectively. There is then a gap, and the last bar starts at 95 and has height 1. The description for this figure is contained within that of the figure above. Choose the two options from the list below that are true. The interval with the highest frequency in the boys' estimates dataset contains a greater number of data values than the
