(B) The given set of numbers is $1, 2, 3, 4, 5$.First,calculate the mean $(\overline{x})$:$\overline{x} = \frac{1 + 2 + 3 + 4 + 5}{5} = \frac{15}{5} = 3$.Next,calculate the mean deviation about the mean using the formula $\frac{\sum |x_i - \overline{x}|}{N}$:$|1 - 3| = 2$$|2 - 3| = 1$$|3 - 3| = 0$$|4 - 3| = 1$$|5 - 3| = 2$Sum of absolute deviations $= 2 + 1 + 0 + 1 + 2 = 6$.Mean deviation $= \frac{6}{5} = 1.2$.

What is the mean deviation of the numbers $1, 2, 3, 4, 5$?
