a farmer weighed a sample of pumpkins from her crop. she recorded the weight (in kg) of each pumpkin. the box - and - whisker plot (sometimes called a boxplot) summarizes these weights. use the box - and - whisker plot to answer the following. (a) what is the heaviest weight? (b) what is the median weight? (c) what is the first quartile (q1) of the weights?
Answer
Explanation:
Step1: Recall box - and - whisker plot properties
In a box - and - whisker plot, the end of the right - hand whisker represents the maximum value (heaviest weight in this case).
Step2: Identify the maximum value
Looking at the plot, the end of the right - hand whisker is at 45 kg.
Step3: Recall median location
The line inside the box represents the median. It is at 30 kg.
Step4: Recall first - quartile location
The left - hand edge of the box represents the first quartile ($Q_1$). It is at 25 kg.
Answer:
(a) 45 kg (b) 30 kg (c) 25 kg
