Math Problem Statement
What is the frequency for the first class (A)?
Solution
The frequency for the first class (A), which corresponds to the interval 80-109, can be determined by counting the number of data points that fall within this range.
Interval 80-109:
The data points within this interval are: 80, 100, 100, 100, 80, 90, 90.
Frequency Calculation:
There are 7 data points in the interval 80-109.
Answer:
The frequency for the first class (A) is 7.
