Answer 1

Answer:

The value of X is 10.

Step-by-step explanation:

For finding the median,

First we put the data in ascending order,

If there are even number of observations,

Then, median = average of two middle terms,

If there are odd number of observations,

Then, median = average of the data.

Here, the given data,

5, 8, 9, X, 11, 13,

∵ Number of observations = 6 ( even ),

Thus, median = $\frac{9+X}{2}$

According to the question,

$\frac{9+X}{2}=9.5$

$9+X=19$

$\implies X = 19 - 9 = 10$

Hence, the value of X is 10.
