Question

Based on the box and whisker plots shown below, which of the following statements is true?

Answer 1

The median of Group A is less than that of Group B

Explanation:

(This is Option A)

Answer 2

1st option is correct.

Step by step explanation:

Let us see our given options one by one.

1. We can see that median of group A is 79 and median of group B is 79.5. Therefore, median of group A is less than group B and 1st statement is correct.

2. Let us find range of each group.

`\text{Range of group A}=82-76=6`

`\text{Range of group B}=81-76=5`

We can see that range of group A is greater than group B, therefore, 2nd statement is false.

3. The lower quartile of group A is 78 and lower quartile of group B is 77. We can see that 78 is greater than 77, therefore, 3rd statement is false.
