For example, if your answer is $345.6671 round as 345.67 and if your answer is .05718 or 5.7182% round as 5.72.   State of the Economy Probability of State Occurring Stock's Expected Return Boom 20% 22.20% Normal 50% 12.90% Recession 30% –11.40%

Senior management of Nancy's Nooks (NN) has determined there is a 20 percent chance EPS will be $7.50 next year, there is a 60 percent chance EPS will be $3.00, and there is a 20 percent chance EPS will be -$3.70. Calculate the expected value, standard deviation, and coefficient of variation for NN's forecasted EPS. Do not round intermediate calculations. Round your answers for the expected value and standard deviation to the nearest cent and for the coefficient of variation to two decimal places. Expected value: $   Standard deviation: $   Coefficient of variation:

Suppose that stock market returns are normally distributed with a mean of 7% and a standard deviation of 20%. There should be about a 16% chance of getting a return less than _______%. Write your answer as a whole number: eg, -15% = -15.

Consider the following information: State of Economy Boom Bust Probability of State of Economy a. Expected return b. Variance .60 .40 Rate of Return if State Occurs % Stock A Stock B .23 .08 .15 .18 a. What is the expected return on an equally weighted portfolio of these three stocks? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) b. What is the variance of a portfolio invested 24 percent each in A and B and 52 percent in C? (Do not round intermediate calculations and round your answer to 6 decimal places, e.g., .161616.) Stock C .42 -.09
