Question
Transcribed Image Text:A survey of major universities asked what percentage of incoming freshmen usually graduate "on time" in 4 years. Use
the summary statistics given to answer the questions.
a) Would you describe this distribution as symmetric or skewed? Explain.
O A. This distribution is skewed, because the mean and median are not reasonably close to one another.
OB.
O B. This distribution is symmetric, because the mean and median are reasonably close to one another
and the extreme values are approximately the same distance from the fences.
