Answer

Explanation:

Step1: Count data in intervals for option A

For the interval 60 - 70: The numbers 67, 65, 66, 69, 68, 69, 62, 64 are in this range, so frequency is 8. For 70 - 80: No numbers in this range, frequency is 0. For 80 - 90: 82, 83, 89, 88, 83, 81, 82, 86, 83, 88 are in this range, frequency is 10. For 90 - 100: 94, 93 are in this range, frequency is 2.

Step2: Check other options

Option B: The intervals are not as standard as option A and the frequency - counting for these non - standard intervals does not match the data distribution as well as option A. Option C: The intervals are not as intuitive as option A and the frequency for sub - intervals within 80 - 90 is split in a non - standard way compared to option A. Option D: The intervals 60 - 75 and 75 - 90 are too wide and do not represent the data as clearly as option A.

Answer:

A. Interval 60-70, Frequency 8; Interval 70-80, Frequency 0; Interval 80-90, Frequency 10; Interval 90-100, Frequency 2
