(a) What was the highest score in the 80s?
(b) What was the lowest score overall?
(c) How many students scored in the 60s?

Answer 1

C is incorrect

Answer 2

To analyze the stem-and-leaf plot:

- The stems represent the tens place, while the leaves represent the ones place of the scores.

From the given information, the scores can be extracted as follows:

- 5 | 8 = 58
- 6 | 4 = 64
- 6 | 9 = 69
- 7 | 0 = 70
- 7 | 1 = 71
- 7 | 5 = 75
- 7 | 9 = 79
- 8 | 4 = 84
- 8 | 8 = 88
- 9 | 0 = 90
- 9 | 1 = 91

Now we can answer the questions:

(a) The highest score in the 80s is **88**.

(b) The lowest score overall is **58**.

(c) To find how many students scored in the 60s, we see the scores 64 and 69. Therefore, **2 students** scored in the 60s.

Answer 3

Let's take a closer look at the scores in the 60s based on the stem-and-leaf plot:

From the previous breakdown, the scores we identified were:
- **6 | 4** = 64
- **6 | 9** = 69

In the stem-and-leaf plot, the only scores in the 60s are:
- 64
- 69

This indicates that there are **2 students** who scored in the 60s.

If you believe the count is incorrect, let's examine how the numbers might have been counted. Based on the list:

1. **64**
2. **69**

These are the only scores listed, confirming that **2 students** scored in the 60s in this case. If you have a different interpretation or clarification on the stem-and-leaf structure, please let me know!
