Question
| a search : e | i Mi Suppose x has a distribution with a mean of s0 and a standard deviation of 9. Random samples of size n 36 are drawn. (a) Describe the x distribution and compute the mean and standard deviation of the distribution. xhas[-Select distribution with mean and standard deviation (b) Find the z value corresponding to (o) Find AR 53) (Round your answer to four decimal places.) (d) Would it be unusual for a random sample of size 36 from the x dstibution to have a sample mean less than s37 Explain. O Yes, it would be unusual because less than s% of all such samples have means less than S3. O No, it would not be unusual because more than 5% of all such samples have means less than 53. O No, it would not be unusual because less than 5% of all such samples have means less than 53. Yes, it would be unusual because more than S% of all such samples have means less than 53.
