c. From the histogram, it appears that the majority of days had 0-4 pieces of mail received at the home, with a smaller number of days having 5-9 pieces of mail. There were only a couple of days with 10-14 pieces of mail and 15-19 pieces of mail. Overall, there is a downward trend in the frequency as the number of pieces of mail increases.
