Question
A simple random sample of size n= 36 is obtained from a population that is skewed right with u= 85 and o= 18. (a) Describe the sampling distribution of x. (b) What is P (x> 88.15) ? (c) What is P (x<77.65)? (d) What is P (81.4 < x< 91.15) ? (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 uniform. O C. The distribution is approximately normal. O D. The distribution is skewed right. O E. The shape of the distribution is unknown. Find the mean and standard deviation of the sampling distribution of x. Ox = (Type integers or decimals. Do not round.) (b) P (x> 88.15) = (Round to four decimal places as needed.)
