![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 \( \sigma^2 \) (the variance of \( x \)) and \( \sigma \) (the standard deviation of \( x \)). Show your work with a table.
