Answer:
To construct a frequency distribution table for the scores of 40 students in a math quiz with a class interval of 5, we need to first organize the scores into classes.
Let's assume the scores are as follows: 70, 75, 80, 83, 85, 88, 90, 92, 95, 98, 100.
1. To find the range of the scores:
Range = Highest Score - Lowest Score
Range = 100 - 70 = 30
2. The class interval with the highest frequency would be the one with the most scores falling within it. This would be determined after organizing the scores into the frequency distribution table.
3. The class interval with the lowest frequency would be the one with the fewest scores falling within it. This would also be determined from the frequency distribution table.
4. To find how many students got scores between 80-84:
We count the number of students falling within the class interval 80-84 after constructing the frequency distribution table.
5. To determine the number of class intervals, we divide the range by the class interval size:
Number of class intervals = Range / Class Interval Size
Number of class intervals = 30 / 5 = 6
After constructing the frequency distribution table and organizing the scores into classes, we can accurately answer questions 2, 3, and 4 based on the data.
