Explanation / Answer

The correct option is c.

Sampling error = population parameter - expected value of the parameter based on sample.

Here population parameter of mean = 2.59 (because it is based on census report).

and the sample mean = 2.53 ( because it is based on sample)

So the estimate of parameter based on the sample is 2.53

So sampling error = 2.59 - 2.53 = 0.06
