Given the probability distributions shown to the right, complete the following parts. Distribution A Distribution B P(X = xi) Xi P(X = x;) 0 0.06 0 0.45 a. Compute the expected value for each distribution. 1 0.11 1 0.25 b. Compute the standard deviation for each distribution. 2 0.13 2 0.13 c. What is the probability that x will be at least 3 in Distribution 3 0.25 3 0.11 A and Distribution B? 4 0.45 4 0.06 d. Compare the results of distributions A and B. a. What is the expected value for distribution A? (Type an integer or decimal rounded to three decimal places as needed.)
