Part 4
d. Compare the sampling error for parts a, b, and c and explain the reason for the differences.
As the sample size increases, the magnitude of sampling error increases.
As the sample size increases, the magnitude of sampling error decreases.
Sample size has no effect on the sampling error.
As the sample size increases, the sampling error becomes increasingly negative.
As the sample size increases, the sampling error becomes increasingly positive.
