Answer 1

Given:

Consider the below figure attached with this question.

To find:

The correct statements about the given box and whisker plot.

Solution:

In a box plot, the left end of the box is first quartile and the right end of the box is third quartile. The line inside the box represents the median.

Left end point represents the minimum value and the right end point represents the maximum value.

From the given box plot, it is clear that

Minimum value = 35

First quartile = 42

Median = 49

Third quartile = 54

Maximum value = 57

The median of the data is 49. The least number of calls is 35. So, options B and C are correct.

The third quartile is represented by 54. So, option D is incorrect.

The mean cannot be determined by the box and whisker plot. So, option E is correct and option A is incorrect.

Therefore, the correct options are B, C and E.
