Consider the five number summary of hourly wages ($) for a sample of advertising / promotion managers. $$\begin{array} { | c | c | c | c | c | }
\hline \text { Min } & \text { Q1 } & \text { Median } & \text { Q3 } & \text { Max } \
\hline 19.64 & 29.36 & 34.18 & 40.86 & 57.26 \
\hline
\end{array}$$ Suppose there had been an error and that the lowest hourly wage was $15.50 instead of
$19)64.This would result in
A)an increase in the median.
B)an increase in the standard deviation.
C)a decrease in the range.
D)a decrease in the IQR.
E)an increase in the mean.
