A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before​ treatment, 18 subjects had a mean wake time of 103.0 min. After​ treatment, the 18 subjects had a mean wake time of 78.4 min and a standard deviation of 20.7 min. Assume that the 18 sample values appear to be from a normally distributed population and construct a 95 ​% confidence interval estimate of the mean wake time for a population with drug treatments. What does the result suggest about the mean wake time of 103.0 min before the​ treatment? Does the drug appear to be​ effective?

Adjusted WACC. Thorpe and Company is currently an​ all-equity firm. It has three million shares selling for $22 per share. Its beta is 0.7​, and the current​ risk-free rate is 2.3​%. The expected return on the market for the coming year is 10.6​%. Thorpe will sell corporate bonds for $22,000,000 and retire common stock with the proceeds. The bonds are​ twenty-year semiannual bonds with a 9.3​% coupon rate and 1,000 par value. The bonds are currently selling for $923.83 per bond. When the bonds are​ sold, the beta of the company will increase to 0.9.

What was the WACC of Thorpe and Company before the bond​ sale? What is the adjusted WACC of Thorpe and Company after the bond sale if the corporate tax rate is 15 %​?

Hint​: The weight of equity before selling the bond is​ 100%.

1. Let W represent a team's win total. Suppose that Major League Baseball instituted a subsidy, S, which is given by S = 0 when W < 90, and is determined by the formula S = 10, 000W when W ≥ 90. Before the subsidy was introduced, the prot-maximizing Detroit Tigers aimed to win 85 games, and the win-maximizing Seattle Mariners aimed to win 95 games. (a) Assuming that the two teams have identical marginal revenue curves, draw a graph that shows MC, MR, and both teams' win totals before the subsidy was introduced. (b) Draw a graph showing the changes that occur due to the introduction of the subsidy. Assume that the subsidy aects MR. (c) How do the win totals change after the subsidy is introduced?

Assignment 3 Question: A 1 m3 rigid tank has propane at 100 kPa and 300 K. The tank is connected to another 0.5 m3 rigid tank which has propane at 250 kPa and 400 K by a ball valve. The valve is opened and both tanks come to a uniform state at 325 K. 1- State all assumptions you need to solve the problem. 2- Calculate the final pressure of propane in both tanks? 3- Calculate the mass of propane before and after opening the valve in each tank. 4- Sketch the process on a P-V diagram. 5- Find the compressibility factor of propane in each tank before opening the valve. 6- Calculate the change in internal energy and enthalpy of propane in each tank.

Larry Burton and his wife Marjorie want to have a baby; however, after several years of trying, Marjorie has not been able to get pregnant. One of Marjorie's friends suggested the try in vitro fertilization (IVF), because she was successful in having a child with this method. "isn't that expensive" ? Marjorie asked. "oh our insurance paid for 80% of the cost,'' her friend responded. What might Larry and Marjorie consider as fa as insurance coverage before undergoing IVF?

A student spends all of her income on pizza and books. When pizzas cost $3 each and books cost $10 each, she consumed 30 pizzas and 3 books per month. The price of pizzas fell to $2.90 each while the price of books rose to $11 each. The price change

a. made her worse off.

b. left her exactly as well off as before.

c. left her at least as well off as before and possibly helped her.

d. might have helped her, might have harmed her. We can’t tell which unless we observe what she consumed after the price change.

e. had the same effect as a $3 increase in her income.
