The mean annual income for adult women in one city is $28,520 and the standard deviation of the incomes is $5,400. The distribution of incomes is skewed to the right. For samples of size 111 determine whether the distribution of x is normal
or approximately normal and give its mean and standard deviation.
O A. Normal, mean p; = $28,520, standard deviation o; = $5,400
O B. Approximately normal, mean p: = $28,520, standard deviation o: = $513
OC. Approximately normal, mean p- = $28,520, standard deviation o
= $5,400
O D. Normal, mean p- = $28,520, standard deviation o- = 513
