An investor is considering the following two investment opportunities. The returns for each, under different economic conditions are forecast as above.

a.    Calculate the expected returns and standard deviation of returns for A and B.

b.    Assume that a portfolio is equally weighted between Investment A and Investment B. What would be the expected return and standard deviation on the portfolio?

c.    Which investment, A, B, or the equally weighted portfolio would you recommend and why?

Hello:

I am working on some homework problems for decision modeling. Here is the question: The weekly deman for a slow moving product has the following probability mass function:

Demand, x Probability f(x)

0 0.2

1 0.4

2 0.3

3 0.1

4 or more 0

Use VLOOKUP to generate 25 random variates from this distribution. I know i have to use RAND and VLOOKUP I just cannot get it to give me 25 random numbers. Thank you for any help you can give me.

Five years ago, a company was considering the purchase of 74 new diesel trucks that were 15.13% more fuel-efficient than the ones the firm is now using. The company uses an average of 10 million gallons of diesel fuel per year at a price of $1.25 per gallon. If the company manages to save on fuel costs, it will save $1.875 million per year (1.5 million gallons at $1.25 per gallon). On this basis, fuel efficiency would save more money as the price of diesel fuel rises (at $1.35 per gallon, the firm would save $2.025 million in total if he buys the new trucks).

Consider two possible forecasts, each of which has an equal chance of being realized. Under assumption #1, diesel prices will stay relatively low; under assumption #2, diesel prices will rise considerably. The 74 new trucks will cost the firm $5 million. Depreciation will be 25.35% in year 1, 38.81% in year 2, and 36.55% in year 3. The firm is in a 39% income tax bracket and uses a 10% cost of capital for cash flow valuation purposes. Interest on debt is ignored. In addition, consider the following forecasts:

Forecast for assumption #1 (low fuel prices):

Required: Calculate the percentage change on the basis that an increase would take place from the NPV under assumption #1 to the probability-weighted (expected) NPV.

Answer% Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places (for example: 28.31%).

To conduct an experiment, a movie theater increased movie ticket prices from $9 to $10 and measured the change in ticket sales. The theater then gathered data over the following month to determine whether the price increase was profitable. Assume total costs to the theater are the same, whether the price of a ticket is $9 or $10.

In order for the ticket price to have been profitable over the month, the elasticity of demand for movie tickets must be (INELASTIC OR ELASTIC) .

Demand curves become (MORE OR LESS) elastic in the long run. This means that the ticket price increase will likely be (MORE OR LESS) profitable in the long run.

This program is broken down into phases for your convenience only. Please turn in only the final phase. Before turning in your program, please make sure that it does something reasonable if the user enters a negative number the first time.

Phase I: Write a program for a theater that will keep track of how many people in each of 5 age categories attended a particular movie. Use the 5 age categories listed below in the sample screen output. The user will enter a number of ages, entering a negative number when there are no more ages to enter. Your program will then report on how many people in each age group attended. Sample screen output:

    Enter age of attendee (-1 to quit): 34    
    Enter age of attendee (-1 to quit): 16
    Enter age of attendee (-1 to quit): 68
    Enter age of attendee (-1 to quit): 53
    Enter age of attendee (-1 to quit): 39
    Enter age of attendee (-1 to quit): 23
    Enter age of attendee (-1 to quit): 21
    Enter age of attendee (-1 to quit): -1

    age 0  to 18: 1
    age 19 to 30: 2
    age 31 to 40: 2
    age 41 to 60: 1
    over 60: 1

Phase II: Modify your program so that, in addition to the report that the program currently produces, it also gives the average age of the people in attendance, the age of the oldest person in attendance, and the age of the youngest person in attendance. Sample screen output:

 
    Enter age of attendee (-1 to quit): 34    
    Enter age of attendee (-1 to quit): 16
    Enter age of attendee (-1 to quit): 68
    Enter age of attendee (-1 to quit): 53
    Enter age of attendee (-1 to quit): 39
    Enter age of attendee (-1 to quit): 23
    Enter age of attendee (-1 to quit): 21
    Enter age of attendee (-1 to quit): -1

    age 0  to 18: 1
    age 19 to 30: 2
    age 31 to 40: 2
    age 41 to 60: 1
    over 60: 1

    The average age was 36.
    The youngest person in attendance was 16.
    The oldest person in attendance was 68.

Phase III: Modify your program so that it also asks each attendee for a theater concession stand purchase. The attendee must make a selection based on the following choices …

1 - Soft Drink (such as Coca Cola, ICCEE, Mineral Water etc...)

2 - Popcorn

3 - Nachos       

4 - Soft drink & Popcorn

5 - Soft drink & Nachos

6 - Organic and Gluten-free snacks       

7 – None

The program output should now also provide a theater concession stand sales summary with a count of each category purchased.

Note: Include a validation routine to ensure that a correct choice is input for each attendee.

Check the sample screen output below for the final formatted display of theater statistics.

DataSpan, Inc., automated its plant at the start of the current year and installed a flexible manufacturing system. The company is also evaluating its suppliers and moving toward Lean Production. Many adjustment problems have been encountered, including problems relating to performance measurement. After much study, the company has decided to use the performance measures below, and it has gathered data relating to these measures for the first four months of operations.

Management has asked for your help in computing throughput time, delivery cycle time, and MCE. The following average times have been logged over the last four months:

Required:

1-a. Compute the throughput time for each month. (Round your answers to 1 decimal place.)

1-b. Compute the manufacturing cycle efficiency (MCE) for each month. (Round your answers to 1 decimal place.)

1-c. Compute the delivery cycle time for each month. (Round your answers to 1 decimal place.)

3-a. Refer to the move time, process time, and so forth, given for month 4. Assume that in month 5 the move time, process time, and so forth, are the same as in month 4, except that through the use of Lean Production the company is able to completely eliminate the queue time during production. Compute the new throughput time and MCE. (Round your answers to 1 decimal place.)

3-b. Refer to the move time, process time, and so forth, given for month 4. Assume in month 6 that the move time, process time, and so forth, are again the same as in month 4, except that the company is able to completely eliminate both the queue time during production and the inspection time. Compute the new throughput time and MCE. (Round your answers to 1 decimal place.)

Laptops:

The table contains created data based off of a research study by Sana and colleagues (2013) in which they investigated the use laptops in college classrooms. Identify the appropriate test to determine if multitasking on a laptop hinders learning, as measured by performance on a comprehension test, compared to those who are not multitasking on a laptop.

2) Identify the appropriate hypothesis test needed to test for statistical significance and state WHY you chose that test. (1 point)

3) Run the test (in SPSS) and upload your output with the portion used to determine significance circled. (2 points)

4) State in words if the result is statistically significant. (1 point)

5) Make the appropriate graph in SPSS (or another computer program) and include the graph in the same file. (2 points)

6) Summarize and interpret your results in 2-3 sentences (using APA format if appropriate). (2 points)

Calculate the contribution to total performance from currency, country, and stock selection for the manager in the example below. All exchange rates are expressed as units of foreign currency that can be purchased with 1 U.S. dollar. (Do not round intermediate calculations. Round your answers to 2 decimal places. Input all amounts as positive values.)
