A simple random sample of size n = 46 is obtained from a population with u = 64 and o = 17.(a) What must be true regarding the distribution of the population in order to use the normal model to compute probabilities involving the sample mean? Assuming that this condition is true, describe the sampling distribution of x.(b) Assuming the normal model can be used, determine P(x< 67.9).(c) Assuming the normal model can be used, determine P(x2 65.9).(a) What must be true regarding the distribution of the population?O A. The population must be normally distributed and the sample size must be large.O B. The population must be normally distributed.O C. The sampling distribution must be assumed to be normal.O D. Since the sample size is large enough, the population distribution does not need to be normal.Assuming the normal model can be used, describe the sampling distribution x. Choose the correct answer below.17O A. Approximately normal, with H: = 64 and o =V46O B. Approximately normal, with H; = 64 and o, = 1746OC. Approximately normal, with H: = 64 and o: =V17(b) P(x < 67.9) =(Round to four decimal places as needed.)(c) P(x2 65.9) =(Round to four decimal places as needed.)

A simple random sample of size n=50 is obtained from a population with a mean of 46 and a standard deviation of 7. Does the population need to be normally distributed for the sampling distribution of x bar to be approximately normally distributed? Why? What is the sampling distribution of x bar?
The thickness (in millimeters) of the coating applied to hard drives is one characteristic that determines the usefulness of the product. When no unusual circumstances are present, the thickness (x) has a normal distribution with a mean of 3 mm and a standard deviation of 0.05 mm. Suppose that the process will be monitored by selecting a random sample of 16 drives from each shift's production and determining x, the mean coating thickness for the sample. (a) Describe the sampling distribution of x for a random sample of size 16. The distribution of x is with mean mm and standard deviation 0.0125 mm. (b) When no unusual circumstances are present, we expect x to be within 2? x of 3 mm, the desired value. An x value farther from 3 mm than 2? x is interpreted as an indication of a problem that needs attention.
