The mean annual income for adult women in one city is $28,520 and the standard deviation of the incomes is $5,000. The distribution of incomes is skewed to the right. For samples of size 105 determine whether the distribution of x is normal or approximately normal and give its mean and standard deviation. O A. Normal, mean H; = $28,520, standard deviation o; = $5,000 O B. Approximately normal, mean H; = $28,520, standard deviation o; = $488 OC. Normal, mean u: = $28,520, standard deviation o; = $488 O D. Approximately normal, mean µ; = $28,520, standard deviation o; = $5,000

Please help me with this question. 

The mean annual income for adult women in one city is $28,520 and the standard deviation of the incomes is $5,000. The distribution of incomes is skewed to the right. For samples of size 105 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; = $5,000 O B. Approximately normal, mean µ; = $28,520, standard deviation o, = $488 OC. Normal, mean µ; = $28,520, standard deviation o; = $488 O D. Approximately normal, mean H; = $28,520, standard deviation o; = $5,000
