Step-by-step explanation:
Here,
number of observations(n) is 10 ...
And, we know that when number of observations is even in given data ...
Then, Median = mean of n/2 and (n/2+1)... (i)
which is , mean of 5th and 6th observations
here, 5th observation is 34 and 6th observation is x...
So, Mean = (34 + x)/2 = median ..... from (i)
Hence, here, median is 35.
So, 35 = (34 + x)/2
So, x = 35 × 2 -34 = 70-34 = 36
so...x is 36
