4. You have the following data set of ages of students in a community college chemistry class. 19 25 20 20 19 20 21 20 19 45 21 21 20 22 19 29 21 21 23 22 18 21 20 34 18 20 20 21 20 23 22 24 19 24 30 19 20 20 21 22 (7 points) A. Create a normal probability plot to determine whether these age data are normally distributed. Offer supporting evidence for your conclusion. (You don't need to draw the plot, but do describe what you see when you make the plot on your calculator.) B. Given what you know about this data, describe the shape of the distribution of ages and comment on the existence of outliers. In this instance, it may be useful to construct a histogram or box-and-whisker plot to find outliers and support your
