Maria Constructed the Frequency Distribution Shown Below She Concluded from Her Frequency Distribution That the Heights 66

Maria constructed the frequency distribution shown below. The data represent the heights of 60 randomly selected women. $$\begin{array} { c c } \text { Height } & \text { Frequency } \\ \hline 54 \text {-under 60 } & 7 \\ \text { 60-under 61 } & 1 \\ \text { 61-under 62 } & 3 \\ \text { 62-under 63 } & 5 \\ \text { 63-under 64 } & 7 \\ \text { 64-under 65 } & 7 \\ \text { 65-under 66 } & 6 \\ 66 \text {-under } 72 & 24 \end{array}$$ She concluded from her frequency distribution that the heights 66, 67, 68, 69, 70, and 71 inches are the most common for women. What is wrong with her conclusion? How is her frequency distribution misleading and how could the table be improved?
