Enter NONE for stems with no leaves.) 5 6 7 8 9 Are there any potential outliers? If so, which scores are they? Why do you consider them outliers? 1.There are no outliers in the data set because there are no large gaps in the stem-and-leaf plot. 2. The two outliers are 50 (because it lies 1.5 × IQR below the first quartile) and 99 (because it lies 1.5 × IQR above the upper quartile). 3.The only outlier is 99 because it is the largest value in the data set. 4.The only outlier is 50 because it lies 1.5 × IQR below the first quartile.arrow_forward
