Problem

A frequency table for the heights of a volleyball squad is given alongside.
<i>Height (H cm)</i><i>Frequency</i>
170≤H<175170 \le H < 1751
175≤H<180175 \le H < 1808
180≤H<185180 \le H < 1859
185≤H<190185 \le H < 19011
190≤H<195190 \le H < 1959
195≤H<200195 \le H < 2003
200≤H<205200 \le H < 2053
(1) Explain why *height* is a continuous variable. (2) Construct a frequency histogram for the data. Carefully mark and label the axes, and include a heading for the graph. (3) What is the modal class? Explain what this means. (4) Describe the distribution of the data.
