Question

what is the range of this set of heights in centimeters? {140, 166, 132, 165, 152, 168, 181, 158, 173, 171, 180, 182, 163, 177, 180, 142, 147, 149, 179}
○ 38
○ 41
○ 46
○ 50

Explanation:

Step1: Find the maximum value

The maximum value in the set \(\{140,166,132,165,152,168,181,158,173,171,180,182,163,177,180,142,147,149,178\}\) is \(182\).

Step2: Find the minimum value

The minimum value in the set is \(132\).

Step3: Calculate the range

The formula for range is \(Range = Max - Min\). So, \(Range=182 - 132=50\).

Answer:

\(50\)
