Given the following information for Watson Power Co., find the WACC. Assume the company’s tax rate is 21 percent.

Debt: 50,000 bonds with a 4.8 percent coupon outstanding, $1,000 par value, 15 years to maturity, selling for 105 percent of par; the bonds make semiannual payments.

Common stock: 975,000 shares outstanding, selling for $42 per share; the beta is 1.11.

Preferred 85,000 shares of 3.8 percent preferred stock outstanding, currently stock: selling for $60 per share.

Assume par value is $105. Market: 7 percent market risk premium and 2.5 percent risk-free rate.

A mass m₁ = 4.4 kg rests on a frictionless table and connected by a massless string over a massless pulley to another mass m₂ = 3.8 kg which hangs freely from the string. When released, the hanging mass falls a distance d = 0.7 m.

1)How much work is done by gravity on the two block system?

2)How much work is done by the normal force on m₁?

3)What is the final speed of the two blocks?

4)How much work is done by tension on m₁?

5)What is the tension in the string as the block falls?

7)What is the NET work done on m₂?

In a study of androstane therapy for treatment of aplastic anemia (AA), neutrophil counts were reported for nine patients with acute severe AA and eight patients with chronic severe AA. These counts are shown in the table below. Do the data provide evidence that the population mean neutrophil count for patients with acute severe AA differs from the population mean neutrophil count for patients with chronic sever AA? Use a 99% confidence level. Explain your answer.

Assume a city has a population of 120,000 individuals. COVID-19 has been found in this city and is estimated to infect 5%, or 6,000, of its citizens in the next month. Local hospitals want to ensure they have enough beds for those cases that require hospitalization.

To make sure they accommodate everyone in a worst-case scenario, they will use the maximum number (the upper bound) of cases requiring hospitalization from the 95% confidence interval reported by the February CDC report cited above (19.1% ± 3.8%) hospitalizations).

How many hospital beds will they need to set aside to house the maximum plausible number of COVID-19 patients?

Researchers investigated the issue of race and equality of access to clinical trials. The following table shows the population distribution and the numbers of participants in clinical trials involving lung cancer. Use a 0.01 significance level to test the claim that the distribution of clinical trial participants fits well with the population distribution. Is ther a race/ethnic group that appears to be very under-represented?

This is my data for a scatterplot. I need to know how to plot the regression line by the NEA data.

1. During the Apollo missions, astronauts traveled from the Earth to the Moon and back. When they were close to Earth, gravity accelerated them toward Earth, but when they were close to the Moon, gravity accelerated them toward the Moon. However, there is a point somewhere between the Earth and the Moon where they experienced no acceleration due to gravity.

   The Earth is 6.0×1024 kg, the Moon is 7.3×1022 kg in mass, and the two are 3.8×108 m apart. How far from Earth were the astronauts when they experienced zero acceleration due to gravity? Hint: remember that zero acceleration requires zero net force.

You want to pay off your mortgage on something called an accelerated bi-weekly payment plan (your parents told you to do this). You have a mortgage of $530,000 amortized over 28 years at a rate of 3.8 percent APR compounded semi-annually. (Assume 52 weeks a year.)

a. What would the regular bi-weekly payment be?

b. What would the accelerated bi-weekly payment be?

c. How much quicker would you pay off the mortgage payment?

d. How much interest would you save by doing the accelerated bi-weekly payment?

1. Brandt Enterprises is considering a new project that has an estimated cost of $900,000 and cash inflows of $286,000 each year in next 5 years. The project’s WACC is 8%. After estimating the cash flows of the project, the CFO conducted a scenario analysis and found the CV (coefficient of variation) of the project’s NPV is 3.8

1. Given that the CV of an average project of the company is in the range of 1.0 to 2.0, how will you interpret the result of the scenario analysis?
2. If the CFO uses a subjective adjustment of 3% in the discount rate to differentiate projects with various risk levels, what will be the risk-adjusted NPV? What do you conclude from the calculation?
