d. Construct a cumulative probability distribution. e. Compute E(X), the expected value of x. Show your work with a table similar to the one on page 62 of the course packet or page 230 of the textbook. You can enter the numbers in Excel and use Excel to construct a table. f. Compute o² (the variance of x) and ♂ (the standard deviation of x). Show your work with a table. Your answer in parts e and f can be in one table.
