For questions 4–5, use the following two ways to display the test scores received on Mr. Alexander's math test. Use these displays to solve each problem.
Stem | Leaf
6 | 8 9
7 | 0 3 5 8 9
8 | 1 2 2 5 7 8 8 9
9 | 0 2 3
Pie Chart:
80-89= 44.4%
90-99=16.6%
70-79=27.7%
60-69=11.1%
4. Which graph shows the lowest score on the test?
A. both graphs
B. only the stem-and-leaf plot
C. only the circle graph
D. Neither of the graphs shows this information.
5. Which graph shows that most of the students earned 80–89 on the test?
A. both graphs
B. only the stem-and-leaf plot
C. only the circle graph
D. Neither of the graphs shows this information.
Can someone please explain how I can work these out. I don't want the answer, I just want help on how I can work it out. Thanks

To answer these questions, you need to understand how to interpret the stem-and-leaf plot and the pie chart.
For question 4, "Which graph shows the lowest score on the test?" you need to look for the graph that indicates the lowest score. To analyze the stem-and-leaf plot, examine the lowest stem value (6) and its corresponding leaf values (8 and 9). To analyze the pie chart, look for the lowest percentage category. By comparing the stem-and-leaf plot and the pie chart, you can determine which graph shows the lowest score.
For question 5, "Which graph shows that most of the students earned 80–89 on the test?" you need to identify the graph that represents the highest percentage range for scores between 80 and 89. Look at the percentage values in the pie chart and consider which range has the greatest percentage. Again, compare this with the stem-and-leaf plot to determine which graph shows that most students earned scores between 80 and 89.
Remember, you should not be looking for the answers directly but instead analyzing the information provided by each graph to arrive at the correct conclusions.
