Question
Suppose a simple random sample of size n 64 is obtained from a population with u 71 and a 16
(a) Describe the sampling distribution of x
(b) What is P (x 73.8)?
(zs08.3)?
(c) What is P
(d) What is P (68.8<x< 75.4)?
(a) Choose the correct description of the shape of the sampling distribution of x
O A. The distribution is skewed right
O B. The distribution is uniform.
O C. The distribution is skewed left.
O D. The distribution is approximately normal.
O E.
The shape of the distribution is unknown
Find the mean and standard deviation of the sampling distribution of x
(b) P (73.8)
(Round to four decimal places as needed.)
(e) P s66.3)
(Round to four decimal places as needed.)
-
(68.8<75.4) =
(d) P
(Round to four decimal places as needed.)
