Question

13. Household income in the United States is strongly skewed to the right. The

current presidential administration claims that the mean household income is
greater than it has ever been in the past. An independent contractor will obtain
a random sample of 100 households in the United States and will calculate the
mean household income. Which of the following statements is true?
(A) The sampling distribution of the sample mean household income is approximately
normal because the sample size of 100 is greater than 30.
(B) The distribution of household income for the sample is approximately normal
because the sample size of 100 is greater than 30.
(C) The sampling distribution of the sample mean household income is strongly
skewed to the right because the population standard deviation is unknown.
(D) The distribution of household income is strongly skewed to the left because the
population sample size of 100 is greater than 30.
(E) The sampling distribution of the sample mean household income is strongly skewed
to the right because the population distribution is strongly skewed to the right​
