Question

adam works at the gray empire parking garage. on saturday, he recorded how long a sample of 15 cars were parked. he did the same on sunday. the results are recorded in the box plots. complete the table. write your answers as whole numbers or decimals rounded to the nearest tenth.

Explanation:

Step1: Find the median for Sunday

The median is the middle line in the box - and - whisker plot. For Sunday's box - and - whisker plot, the median is \(2\).

Step2: Find the inter - quartile range for Saturday

The inter - quartile range (IQR) is calculated as \(Q_{3}-Q_{1}\). For Saturday's box - and - whisker plot, \(Q_{3} = 5\) and \(Q_{1}=3\). So \(IQR=5 - 3=2\).

Answer:

Sunday's median: \(2\); Saturday's inter - quartile range: \(2\)
