Calculate the variance version of standard error for each sample in Exercise 10.18—for the liberals (2, 1, 3, 2) and then for the conservatives (4, 3, 3, 5, 2, 4).

Steps to calculate the variance version of standard error:
1. Square the standard error.
2. Multiply the square of the standard error by the sample size.
The result should be the variance of the sample.
