Question

use the box - and - whisker plot to answer the following.(a) what is the median weight?(b) what is the lightest weight?(c) what is the first quartile ($q_1$) of the weights?

Explanation:

Step1: Recall box - and - whisker plot properties

In a box - and - whisker plot, the line inside the box represents the median.

Step2: Identify the median

By looking at the plot, the line inside the box is at \(29\) kg.

Step3: Recall the minimum value property

The left - most end of the whisker (not including outliers if any) represents the minimum (lightest) value.

Step4: Identify the lightest weight

The left - most end of the whisker is at \(17\) kg.

Step5: Recall the first quartile property

The left - hand side of the box represents the first quartile (\(Q_1\)).

Step6: Identify the first quartile

By looking at the plot, the left - hand side of the box is at \(22\) kg.

Answer:

(a) \(29\) kg
(b) \(17\) kg
(c) \(22\) kg
