Question

italian tours offers a daily sightseeing trip around florence. the list below
21, 26, 38, 47, 43, 18, 46, 21, 18
find the range of the data set.

Explanation:

Step1: Find the maximum value

First, we look through the data set \(21, 26, 38, 47, 43, 18, 46, 21, 18\). The maximum value \(M\) is \(47\).

Step2: Find the minimum value

Then, we look for the minimum value \(m\) in the data set. The minimum value \(m\) is \(18\).

Step3: Calculate the range

The formula for the range \(R\) of a data set is \(R = M - m\). Substituting \(M = 47\) and \(m = 18\) into the formula, we get \(R=47 - 18\).

Answer:

\(29\)
