The number of raisins in each of 14 miniboxes (1/2-ounce size) was counted for a generic brand and for Sun maid brand raisins. The two data sets are shown here:

For Information: Refer to Exercise 2.54.
a. Find the median, the upper and lower quartiles, and the IQR for each of the two data sets.
b. Construct two box plots on the same horizontal scale to compare the two sets of data.
c. Draw two stem and leaf plots to depict the shapes of the two data sets. Do the box plots in part b verify these results?
d. If we can assume that none of the boxes of raisins are being under-filled (that is, they all weigh approximately 1/2 ounce), what do your results say about the average number of raisins for the two brands?
