Suppose x has a distribution with a mean of 50 and a standard deviation of 21. Random samples of size n = 36 are drawn. (a) Describe the x distribution and compute the mean and standard deviation of the distribution. x has a normal distribution with mean = 50 (b) Find the z value corresponding to x = 43. z= and standard deviation 0-3.5 (c) Find P(x <43). (Round your answer to four decimal places.) P(x < 43)= (d) Would it be unusual for a random sample of size 36 from the x distribution to have a sample mean less than 43? Explain. No, it would not be unusual because more than 5% of all such samples have means less than 43. Yes, it would be unusual because more than 5% of all such samples have means less than 43. No, it would not be unusual because less than 5% of all such samples have means less than 43. Yes, it would be unusual because less than 5% of all such samples have means less than 43.
