## Text Solution

Steps:

(i) True: Mode is the observations that occurs highest numbers of times. Therefore, it is one observation in a data.

(ii) False: Mean may or may not be one of the numbers in a data.

(iii) True: Median is the middle observations of the given data when it is arranged in ascending or descending order.

(iv) False: The given data $$6, 4, 3, 8, 9, 12, 13, 9.$$

\begin{align} \text{Mean} & =\frac{\left[ \begin{align} & 6+4+3+8+ \\& 9+12+13+9 \\\end{align} \right]}{8} \\ & =\frac{64}{8} \\ & =8 \\\end{align}

Therefore, mean is $$8.$$
