Question

the scores on a recent statistics exam are shown below. which student constructed a correct ordered stem and leaf plot? 98, 73, 64, 69, 86, 89, 77, 86, 91, 73

Explanation:

Step1: Understand stem - and - leaf plot

In a stem - and - leaf plot, the stem is the tens digit and the leaf is the units digit.

Step2: Order the data

The data set is \(64,69,73,73,77,86,86,89,91,98\).

Step3: Analyze the stems and leaves

For the 60s: stems are 6, leaves are 4,9. For the 70s: stems are 7, leaves are 3,3,7. For the 80s: stems are 8, leaves are 6,6,9. For the 90s: stems are 9, leaves are 1,8.

Step4: Check the plots

We need to check which plot has the correct stems and leaves in order.

Answer:

(Without seeing the full - clarity of the options, we can't give a specific option. But the correct plot should have 6 | 4 9; 7 | 3 3 7; 8 | 6 6 9; 9 | 1 8 where the left - hand side of the vertical line is the stem and the right - hand side are the leaves in ascending order for each stem.)
