13. The dot plot in Figure 15.21 represents the num- ber of small candies found in several packets 23 24 25 21 22 Figure 15.21 Dot plot of the number of candies in packets 20 Michael found the mean number of candies in packet by calculating this way 21+22+23 = 22 3 Anne found the mean number of candies in a packet by calculating this way: 4+7+5 3 Is either of these methods correct? If not, ex plain what is wrong, and explain how to calcu- late the mean number of candies in the packets correctly
