(i) True.

Mode is the observation which occurs maximum number of times.

Hence, Mode will always be the one of the numbers in a data.

(ii) False.

(iii) False.

For even number of observations, the median is the mean of the \frac{n}{2}^{th} and\left (\frac{n+1}{2} \right )^{th} values.

(iv) Mean = \frac{Sum\ of\ observations}{Number\ of\ observations}

\\ = \frac{6+ 4+ 3+ 8+ 9+ 12+ 13+ 9}{8} \\ = \frac{64}{8} \\ \\ = 8

Hence, the statement is False.
