Question

Consider the set {4, 5, 7, 8, 8, 12, 13, 13, 15, 18, 20, 22, 24, 26, 27, 37, 38}. if you were dividing the set into intervals, which is the best interval for the first subset of data?
A) 0-7
B) 4-5
C) 4-12
D) 0-10

Answer 1

Answer:

C) 4-12

Step-by-step explanation:

A) 0-7

Its frequency will only be 3 and there are no numbers from 0 till 3 therefore, this is not the best interval.

B) 4-5

This interval is too short. If you go on with the intervals, there will be a lot of sets. Therefore, this is not right.

C) 4-12

The set starts from 4 and so does the interval. The interval 4-12 will have a frequency of 6 and the next intervals will be 13-21, 22-30, 31-39.

Therefore, this is the best interval for the data.

D) 0-10

There are no numbers from 0-3 or 9-10, therefore this is not the best interval.

The correct answer is option C) 4-12
