A) This statement is incorrect. A probability sample can give you a result within several standard errors of the true value in the population, but there is no guarantee that it will be within one standard error.
B) This statement is also incorrect. Most variables are not normally distributed in the population, and sampling distributions often tend towards normality as the sample size increases.
Therefore, neither statement is correct and the correct answer is D.
