Question

here is a list of students test scores. 100, 71, 87, 90, 100, 75, 70, 83, 89, 88, 94. which number belongs in the blank below? test scores

7	0, 1, 5
8	__, 7, 8, 9
9	0, 4
10	0, 0	key: 7	1 means 71

Explanation:

Step1: Understand the stem - and - leaf plot

In a stem - and - leaf plot, the left - hand column is the stem and the right - hand column is the leaf. The key shows that \(7|1\) means \(71\). We need to find the missing leaf for the stem of \(8\) from the list of test scores \(100,71,87,90,100,75,70,83,89,88,94\).

Step2: Identify the scores with stem 8

The scores with stem \(8\) from the list are \(87,83,89,88\). The missing leaf value for the stem \(8\) in the given plot among these values is \(3\).

Answer:
