Which of the following is a definitely a true statement?
This distribution must be symmetric because the mean and the median are so close
About 71 of the observations are less than 43.
Since the interval from the median to 5 is greater than the interval from the median to 58
there are more observations less than 48 than there are greater than 48.
Since the IQR is greater than the standard deviation, this distribution is likely skewed to
the right
There is at least one outlier
