Answer 2

Answer:

8. Mean is $39.09$, median is $16$ and mode is $16$.

9. Mode is $43$ and $44$. Yes, more than 1 mode exists.

Step-by-step explanation:

8.

Arrange the given data in ascending order.

$1, 7, 9, 11, 16, 16, 16, 51, 81, 101, 121$

Since number of observation, $n=11$

Mean = sum of observation/number of observation

          $=\frac{1+7+9+11+16+16+16+51+81+101+121}{11}$

          $=\frac{430}{11}$

          $=39.09$

Therefore, mean is $39.09$.

So, median = $\frac{n+1}{2}$, where $n$ is the number of observation.

⇒ median = $\frac{11+1}{2}$

⇒ median = $\frac{12}{2}$

                 = $6^{th}$ observation

Therefore, $16$ is the median.

Observe that $16$ is the only number that repeats maximum number times, i.e., $3$ times.

Therefore, mode is $16$.

9.

Arrange the given data in ascending order.

$33, 36, 38, 39, 43, 43, 44, 44, 46, 51$

Observe that $43$ and $44$ are the numbers that repeats maximum number times, i.e., $2$ times.

Therefore, mode is $43$ and $44$.

Yes, there is more than 1 mode because $43$ and $44$ occurs equal number times.
