Use regression analysis to estimate the market model for Company A and Company B, and the equally weighted portfolio.

a. Interpret the regression slope coefficient (beta) in the context of the market model for each of the 3 assets.

b. Interpret the coefficients of determination (R²) in the context of the market model (systematic and nonsystematic risk).

The calculations can be done with Excel’s Data Analysis “Regression” function, clicking on “Line Fit Plots” in the dialogue box to see the fitted line.

The benefits of the new system are expected to come from two sources: increased occupancy and ability to charge additional rent due to convenience. The benefit from occupancy is expected to total $30,000 in the first year of the system’s operation, and will grow at a rate of 10% per year. Rental increase is expected to realize $15,000 per year. Assume that personnel costs rise at 4%/year.
Following the model presented in the lecture, develop a spreadsheet that summarizes the project’s cash flow, assuming a four-year payback period after the project is developed.
Following the model presented in the lecture, compute the present value of the cash flows using an interest rate of 4%.

Given the following dataset x   1   1   2   3   4   5

y   0   2   4   5   5   3

We want to test the claim that there is a correlation between xand y. The level of cretaine phosphokinase (CPK) in blood samples measures the amount of muscle damage for athletes. At Jock State University, the level of CPK was determined for each of 25 football players and 15 soccer players before and after practice. The two groups of athletes are trained independently. The data summary is as follows :For football players : n=25 before practice  after practice   difference(before-after)

mean   254.73   225.6   29.13

St.deviation   115.5   132.6   21.00

For soccer players

n=15   before practice   after practice   difference(before-after)

mean   177.1   173.8   3.3

st.deviation   60.7   64.4   6.88

7. Construct a 95% Confidence Interval for the difference in mean CPK values for foot-ball players and soccer players BEFORE exercises.

8. Construct a 95% Confidence Interval for the difference in mean CPK values for foot-ball players BEFORE and AFTER exercises.

9. Test the claim that the mean CPK level has DECREASED for soccer players AFTERexercise (compared to the mean BEFORE exercise), using α= 0.10.

10. AFTER practice, do football players have a DIFFERENT mean CPK values com-pared to soccer players? Test this claim by performing a hypothesis test, usingα= 0.10.

An electromagnet can be modeled as an inductor in series with a resistor. Consider a large electromagnet of inductance L = 12.5 H and resistance R = 3.00 Ωconnected to a 24.0-V battery and switch as in the figure shown below. After the switch is closed, find the following.

(a) the maximum current carried by the electromagnet

(b) the time constant of the circuit

(c) the time it takes the current to reach 95.0% of its maximum value

Acrolein (propenal) is an important industrial compound and used as a contact herbicide. It has a vapour pressure of 259.8 Torr at 25.0 °C. The occupational exposure limit is 100 ppbv over 8 hours. A major spill of acrolein occurs in a closed room without ventilation at 25.0 °C and 1.00 atm. Determine the mixing ratio of acrolein in the room air (by volume) after steady state is reached.

Ohio, along with many other states as well as other countries, has issued Stay-at-Home orders. Colleges have closed campus and many may have moved back to home communities. Answer the following questions:

1) Should first responders (i.e.: Police Officers and/or Fire Fighters) get “hazard pay” during the Pandemic. If so, how much and how do you propose to finance the extra cost? If not, why not? If your community does not have a police or fire department, what impact do you think the Pandemic will have on current government operations and services of your community?

2) What impact is the COVID-19 Pandemic likely to have on the financial results of the community for 2020 and 2021?
