Heights of students in centimeters were obtained for a study. The last digits of those heights are listed. Construct a histogram with 10 classes. What can you conclude from the distribution of the digits?
0 0 0 0 0 0 0 0 0 1 1 2 3 3 3 4 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 6 6 8 8 8 9
A.) The digits of 0 and 5 occur disproportionately more often than the others; it appears that the heights were reported, not measured.
B.) The classes 0 and 5 have the highest frequencies; we can conclude that most student heights have measurements that end in a 0 or 5 cm.
C.)The choice of 10 classes was a poor choice; nothing can be concluded from this histogram.
D.)This is a small sample; a histogram is not an appropriate way to display the data.
