Question

the ages (in years) of a random sample of shoppers at a gaming store are shown. determine the range, mean, variance, and standard deviation of the sample data set
12, 15, 23, 14, 14, 17, 21, 18, 13, 17
the range is
(simplify your answer.)

Explanation:

Step1: Find the maximum and minimum values

The given data set is \(12, 15, 23, 14, 14, 17, 21, 18, 13, 17\).
The maximum value \(M = 23\), the minimum value \(m=12\).

Step2: Calculate the range

The formula for the range \(R\) of a data - set is \(R = M - m\).
Substitute \(M = 23\) and \(m = 12\) into the formula: \(R=23 - 12\).

Answer:

\(11\)
