(A) Given the set of numbers: $3, 4, 5, 6, 7$.First,calculate the mean $(\bar{x})$:$\bar{x} = \frac{3 + 4 + 5 + 6 + 7}{5} = \frac{25}{5} = 5$.Next,calculate the mean deviation about the mean using the formula: $	ext{Mean Deviation} = \frac{\sum |x_i - \bar{x}|}{n}$.$	ext{Mean Deviation} = \frac{1}{5} [|3 - 5| + |4 - 5| + |5 - 5| + |6 - 5| + |7 - 5|]$.$= \frac{1}{5} [|-2| + |-1| + |0| + |1| + |2|]$.$= \frac{1}{5} [2 + 1 + 0 + 1 + 2] = \frac{6}{5} = 1.2$.
