Solve the problem.
-Among a random sample of 150 employees of a particular company, the mean commute distance is 25.4 miles. this mean lies 1.7 standard deviation(s)below the mean of the sampling distribution. In a second sample of 150 employees selected from the same company, the mean commute distance is 31.7 miles. This second sample mean lies 2 standard deviation(s)above the mean of the sampling distribution. If a third sample of 150 employees is selected, what is the probability that the sample mean will lie between 25.4 and 31.7?
A)0.9772
B)0.9326
C)0.0218
D)0.0446
