Consider the following probability distribution. Complete parts a through d. X 11 w/ - + w/ - . p(x) W / - a. Calculate up for this distribution. 5.33 (Round to the nearest hundredth as needed.) b. Find the sampling distribution of the sample mean x for a random sample of n = 3 measurements from this distribution. Put the answers in ascending order for x. p(x) (Type an integer or a simplified fraction.)
