Explanation:

Step1: Calculate the mean

First, find the sum of the data set: \(56 + 21 + 48 + 17 + 18\). Let's compute that: \(56+21 = 77\), \(77 + 48 = 125\), \(125 + 17 = 142\), \(142 + 18 = 160\). Then, the mean is the sum divided by the number of data points (which is 5). So, mean \(=\frac{160}{5}=32\). Wait, no, wait: \(56 + 21 = 77\), \(77 + 48 = 125\), \(125 + 17 = 142\), \(142 + 18 = 160\)? Wait, 56+21 is 77, 77+48 is 125, 125+17 is 142, 142+18 is 160? Wait, 56+21=77, 77+48=125, 125+17=142, 142+18=160? Wait, 56+21=77, 77+48=125, 125+17=142, 142+18=160? Wait, 56+21=77, 77+48=125, 125+17=142, 142+18=160?
