Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Question

100%

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
