• A. 1
• B. 5
• C. 8
• D. 6
• E. 3

Answer 1

Answer: (A), (C)

The correct options are
A 1
C 8

We can define the range as the difference between the highest value and the lowest value.

Let us consider the given dataset 3, 4, 4, 5, 9, 10.
Here, the highest and the lowest observations are 10 and 3 respectively.
Thus, range of the dataset = 11 - 3 = 8.

The frequency of an entry is the number of times the entry occurs in the dataset.
Since observation '5' occurs only one time, its frequency is 1.
