Chapter 1.2, Problem 70E

To determine

To find: The missing number

Answer to Problem 70E

The missing number is 92.

Explanation of Solution

Given:

  $84\text{ 76 92 92 88 96 68 80 92 88 76 96}$

6 8

7 6 6

8 0 4 8 8

9 2 2 6 6

Calculation:

In the stemplot, $\frac{a}{b}$ means that $a$ is the digit of the tens $b$ is the digit of the ones.

The values given in the stemplot are then:

  $68,78,76,80,84,88,88,92,92,96,96$

We note that the stemplot then contains 92 twice, while the dataset contains 92 trice.

Therefore, the missing number is 92.
