wednesday6045
thursday3040
friday3530

how can kate figure out which week had the larger range in minutes read?
\\(\bigcirc\\) 1. order the minutes for each week.

  1. find the range for each week.
  2. compare the ranges.

week 1 had the larger range in minutes.

Explanation:

Step1: Recall range calculation rule

Range = Max value - Min value

Step2: Calculate Week 1 range

First, identify Week 1 values: 85, 35, 50, 60, 30, 35, 50. Max = 85, Min = 30.
$\text{Range}_1 = 85 - 30 = 55$

Step3: Calculate Week 2 range

Identify Week 2 values: 55, 50, 45, 45, 40, 30, 50. Max = 55, Min = 30.
$\text{Range}_2 = 55 - 30 = 25$

Step4: Compare the two ranges

$55 > 25$, so Week 1 has larger range.

Answer:

  1. Order the minutes for each week.
  2. Find the range for each week.
  3. Compare the ranges.

Week 1 had the larger range in minutes.
