Question
A simple random sample of size n= 36 is obtained from a population that is skewed right with u = 85 and o = 24.
(a) Describe the sampling distribution of x.
(b) What is P (x> 89.8) ?
(c) What is P (xs76.2)?
(d) What is P (80.4 <x< 92.2) ?
(a) Choose the correct description of the shape of the sampling distribution of x.
O A. The distribution is skewed left.
O B. The distribution is approximately normal.
OC. The distribution is skewed right.
O D. The distribution is uniform.
O E. The shape of the distribution is unknown.
Find the mean and standard deviation of the sampling distribution of x.
o; =
(Type integers or decimals. Do not round.)
(b) P (x> 89.8) = (Round to four decimal places as needed.)
(c) P (xs76.2) = (Round to four decimal places as needed.)
(d) P (80.4 <x< 92.2)
(Round to four decimal places as needed.)
