Math Problem Statement
Solution
Let's analyze the updated image to confirm the details and ensure accuracy in the answers:
-
Histogram Analysis (rechecking frequencies)
- Interval 67–74: Frequency = 4
- Interval 75–82: Frequency = 4
- Interval 83–90: Frequency = 7
- Interval 91–98: Frequency = 3
- Interval 99–106: Frequency = 2
Total Frequency = 4 + 4 + 7 + 3 + 2 = 20
-
Reconfirm Relative Frequency Calculations
a. Relative Frequency for Scores 75–82
- Frequency for 75–82 = 4
- Relative Frequency =
b. Relative Frequency for Scores 91–106
- Combined frequency for intervals 91–98 and 99–106 = 3 + 2 = 5
- Relative Frequency for 91–106 =
Final Confirmed Answers:
- a. Relative frequency of scores 75–82 = 0.20
- b. Relative frequency of scores 91–106 = 0.25
