FIGURE 14.23
A Dot Plot of the Number of Candies in Packets
John found the mean number of candies in a packet by calculating this way:
$\frac{21+22+23}{3} = 22$
Anne found the mean number of candies in a packet by calculating this way:
$\frac{4+7+5}{3} = 5\frac{1}{3}$
Is either of these methods correct? If not, explain what is wrong, and explain
how to calculate the mean number of candies in the packets correctly.

FIGURE 14.23
A Dot Plot of the Number of Candies in Packets
John found the mean number of candies in a packet by calculating this way:
(21+22+23)/(3) = 22
Anne found the mean number of candies in a packet by calculating this way:
(4+7+5)/(3) = 5(1)/(3)
Is either of these methods correct? If not, explain what is wrong, and explain
how to calculate the mean number of candies in the packets correctly.

Step 1

He simply states the number 3 as the mean without any explanation or calculation. This is not a valid method for finding the mean. Step 2: Anne's method of calculating the mean number of candies in a packet is also incorrect. She adds up the numbers 4, 7, and Show more…
