You own a portfolio of two stocks. Red River Inc. has an expected return of 9% and a standard deviation of 15% while Boston Harbor Co. has an expected return of 15% with a standard deviation of 19%.

a. What percent of your portfolio must you invest in each stock if you wanted to earn a 12.4% return on the portfolio? (Hint: Consider W1+W2=1.0)

b. If the correlation coefficient is 0.3, what is the standard deviation of this portfolio? Is risk reduced at these weights relative to the risk of the individual assets? Why?

Medical marijuana is a controversial subject that appears in the news on a regular basis. Should it be legalized for medical purposes, for any purpose (like in Colorado), or should the new strain of Cannabis (Charlotte’s Web), which has less than 0.3% THC (this is the chemical that creates the high) be used instead? The formal paper for this class will discuss the two types of marijuana and whether either one should be legalized for medical purposes or legalized for general purposes. Meet the page of 3-4 pages

3. A random sample of wolf dens in the southwestern United States is taken. The number of pups found are:

5 8 7 5 3 4 3 9 5 8 5 6 5 6 4 7

a. Find a 90% confidence interval for the population mean number of wolf pups per den. Include the sample statistics, degrees of freedom, LaTeX: t_{\frac{\alpha}{2}}t α 2 , standard error and a sentence.
b. What sample size is needed for the margin of error to be 0.3?

Roger has a levered cost of equity of 0.18. He is thinking of investing in a project with upfront costs of $8 million, which pays $1 million per year for the next 8 years. He is going to borrow $2 million to offset the startup costs at a rate of 0.08. His tax rate is 0.3. He will repay this loan at the end of the project. What is the NPV of this project, using the FTE method?

A journal published a study of the lifestyles of visually impaired students. Using​ diaries, the students kept track of several​ variables, including number of hours of sleep obtained in a typical day. These visually impaired students had a mean of 9.06hours and a standard deviation of 2.11 hours. Assume that the distribution of the number of hours of sleep for this group of students is approximately normal. Complete parts a through c.

A price quote for equipment at Paul Engineering has been received at a cost of $100,000. The operation and maintenance costs of this equipment are estimated to be about $20,000 per year. Salvage value is expected to be $10,000 when the machine is retired. The life of this equipment is estimated to vary anywhere from 5 to 9 years with the associated probabilities as shown in the table below. If the interest rate is 10%, what is the expected EUAC for this equipment?

Demand data on "Service Orders" for a particular service enterprise for the previous 12 months is as follows: 550, 652, 673, 707, 725, 752, 780, 797, 815, 836, 850, and 872. Problem 3b) Use the following three methods and prepare three forecasting tables with errors for the given demand data. • a 3-month Weighted Moving Average with the weights 0.6, 0.3, and 0.1 with the maximum weight going for the most recent data point into the past • Exponential Smoothing with smoothing constant = 0.9 • Linear Trend Regression

A salesman has scheduled two appointments to sell encyclopedias. His first appointment will lead to a sale with probability 0.3, and his second appointment will lead independently to a sale with probability 0.6. Any sale made is equally likely to be either for the deluxe model, which costs $1000, or the standard model, which costs $500. X is the total dollar value of all sales. Hint: you could find the probability mass function of X and use that.
