Here are summary statistics for the time,in minutes,it took 21 students to write a statistics test. $\begin{array} { c | c | c | c | c | c | c | c }
\text { Count } & \text { Mean } & \text { Median } & \text { StdDev } & \text { Min } & \text { Max } & \text { Q1 } & \text { Q3 } \
\hline 21 & 23.9 & 22.0 & 12.2 & 5.1 & 51.7 & 15.4 & 33.4
\end{array}$ Would you describe this distribution as symmetric or skewed?
A)Skewed to the right,because the mean is much larger than the median and the upper quartile is farther from the median than the lower quartile.
B)Symmetric,because the mean and the median are close.
C)Skewed to the right,because the mean is much larger than the median and the lower quartile is farther from the median than the upper quartile.
D)Skewed to the left,because the mean is much larger than the median and the lower quartile is farther from the median than the upper quartile.
E)Skewed to the left,because the mean is much larger than the median and the upper quartile is farther from the median than the lower quartile.

The distribution is skewed to the right because the mean (23.9) is greater than the median (22.0), indicating a longer tail to the right. Additionally, the distance from the third quartile (Q3) to the median is greater than the distance from the first quartile (Q1) to the median, further indicating a right skew.
