(D) The mean is calculated using the formula $	ext{Mean} = \frac{\sum x_i f_i}{\sum f_i}$.Given values $x_i = \{1, \frac{1}{2}, \frac{1}{3}, \dots, \frac{1}{n}\}$ and frequencies $f_i = \{1, 2, 3, \dots, n\}$.Sum of products $\sum x_i f_i = (1 	imes 1) + (\frac{1}{2} 	imes 2) + (\frac{1}{3} 	imes 3) + \dots + (\frac{1}{n} 	imes n) = 1 + 1 + 1 + \dots + 1$ ($n$ times) $= n$.Sum of frequencies $\sum f_i = 1 + 2 + 3 + \dots + n = \frac{n(n + 1)}{2}$.Therefore,$	ext{Mean} = \frac{n}{\frac{n(n + 1)}{2}} = \frac{2n}{n(n + 1)} = \frac{2}{n + 1}$.

If the values $1, \frac{1}{2}, \frac{1}{3}, \dots, \frac{1}{n}$ have frequencies $1, 2, 3, \dots, n$ respectively,what is their mean?
