1. (3 POINTS) An insurance policy pays a individual $500 per day for up to 3 days of hospitalization and $100 per day for each day of hospitalization thereafter. The number of days of hospitalization is a random variable X with P(X=x) = (6-x)/15, if x = 1,2,3,4,5. Calculate the expected payment for hospitalization under this policy. 2.

Problem 3 (10 points). What are the expected value and variance of the number of full house hands in 100 poker hands? A poker hand consists of five randomly selected cards from an ordinary deck of 52 cards. It is a full house if three cards are of one denomination and two cards are of another denomination: for example, three queens and two 4's Problem 4 (10 points). Let X be a binomial random variable with parameters n 15 and...

Compute the expected return, standard deviation, beta, and nonsystematic standard deviation of the portfolio. 4. Assume that the total market value of an initial portfolio is $300,000. Suppose that the owner of this portfolio wishes to decrease risk by reducing the allocation to the risky portfolio from y = 0.7 to y = 0.56. How do you reallocate your risky portfolio? 5. Which of the following factors reflect pure market risk for a given corporation? a. Increased short-term interest rates....

Compute the mean and standard deviation for the following sample of n = 4 scores: 82, 88, 82, 86 (Hint: To simplify the arithmetic, you can subtract 80 points from each score to obtain a new sample consisting of 2, 8, 2, and 6.) Compute the mean and standard deviation for the new sample. Mean: Standard deviation: What are the values of the mean and standard deviation for the original sample? Mean: Standard deviation:
