Question

based on the following calculator output, determine the range of the dataset. 1 - var - stats (overline { x } = 40.55882352941177) (sum x = 6895) (sum x ^ { 2 } = 296989) (s x = 10.128146896371154) (sigma x = 10.098314292845782) (n = 170) (minx = 21) (q _ { 1 } = 33) (med = 41.5) (q _ { 3 } = 47) (maxx = 63)

Explanation:

Step1: Recall the formula for range

The range of a dataset is calculated as \( \text{Range}=\text{maxX}-\text{minX} \).

Step2: Substitute the values of maxX and minX

We are given that \( \text{minX} = 21 \) and \( \text{maxX}=63 \).
So, \( \text{Range}=63 - 21 \).

Step3: Calculate the result

\(63-21=42\).

Answer:

42
