Answer :

Median = 198.5

Step-by-step explanation:

First, let's arrange the population values in ascending order:

20, 65, 92, 131, 142, 143, 147, 149, 153, 160, 176, 176, 178, 181, 193, 193, 204, 213, 239, 248, 260, 263, 302, 360, 384, 387, 391, 407, 437, 522, 591, 672, 733, 777, 1490

Now, since there are 36 data points, which is an even number, the median will be the average of the 18th and 19th values.

The 18th value is 193 and the 19 value is 204.

Median=  (193 + 204) / 2

= 397/2

= 198.5
