Vedclass · Answer

(D) The harmonic mean $(H.M.)$ of $n$ observations $x_1, x_2, ..., x_n$ is given by the formula:$H.M. = \frac{n}{\sum_{i=1}^{n} \frac{1}{x_i}} = \frac{n}{\frac{1}{x_1} + \frac{1}{x_2} + ... + \frac{1}{x_n}}$Here,$n = 5$ and the observations are $3, 7, 8, 10, 14$.Substituting these values into the formula:$H.M. = \frac{5}{\frac{1}{3} + \frac{1}{7} + \frac{1}{8} + \frac{1}{10} + \frac{1}{14}}$Thus,the correct option is $D$.

The harmonic mean of $3, 7, 8, 10, 14$ is
