Question

A company collected the ages from a random sample of its middle managers,with the resulting frequency distribution shown below. $\begin{array} { l r } 
\text { Class Interval } & \text { Frequency } \
20 \text { to } < 25 & 8 \
25 \text { to } < 30 & 6 \
30 \text { to } < 35 & 5 \
35 \text { to } < 40 & 12 \
40 \text { to } < 45 & 15 \
45 \text { to } < 50 & 7
\end{array}$
What would be the approximate shape of the relative frequency histogram?
A)Symmetrical
B)Uniform
C)Multiple peaks
D)Skewed to the left
E)Skewed to the right

Looking at the frequency distribution we see that there are more managers in the older age groups (40 to <45 and 35 to <40) and fewer in the younger age groups (20 to < 25 and 25 to < 30). This suggests that the distribution is skewed to the left. Therefore, the best choice is D) Skewed to the left.
