Math Problem Statement
answer part a is 5/22 what is part b?
Solution
To find the answer for part (b), which asks for the relative frequency of scores between 83 and 98, let's examine the histogram data provided in the image.
-
Identify frequencies for the intervals 83–90 and 91–98:
- For the interval 83–90, the frequency is 7.
- For the interval 91–98, the frequency is 3.
-
Calculate the total frequency of scores between 83 and 98:
-
Determine the total frequency of all intervals: By adding up the frequencies for each interval:
- 67–74: 5
- 75–82: 4
- 83–90: 7
- 91–98: 3
- 99–106: 3
Total frequency:
-
Calculate the relative frequency for scores between 83 and 98: The relative frequency is the frequency of scores from 83 to 98 divided by the total frequency:
Therefore, the relative frequency for scores between 83 and 98 is .
