For the purposes of constructing modified boxplots, outliers are defined as data values that are above upper q 3 by an amount greater than 1.5 times iqr or below upper q 1 by an amount greater than 1.5 times iqr, where iqr is the interquartile range. using this definition of outliers, find the probability that when a value is randomly selected from a normal distribution, it is an outlier.
