Problem # 2

Each of two mutually exclusive projects involves an investment of $ 75,000.  

The cash flows for the projects are as follows:

                                         Year              Project “A”                  Project "B"

                                            1                      29,000                        42,000

                                            2                      29,000                        42,000

                                            3                      29,000                        42,000

                                            4                      29,000

               Note: Project "A" covers 4 years and project "B" covers 3 years.                              

        A.   Calculate each project's payback period.          1 point        

                    B.   Compute the IRR of each project. 1 Point

Copier maintenance. The Tri-City Office Equipment Corporation sells an imported copier on a franchise basis and performs preventive maintenance and repair service on this copier. The data below have been collected from 45 recent calls on users to perform routine preventive maintenance service; for each call, X is the number of copiers serviced and Y is the total number of minutes spent by the service person. Assume that first-order regression model (1.1) is appropriate. (a) Obtain the estimated regression function. (b) Plot the estimated regression function and the data. How well does the estimated regression function fit the data? (c) Interpret b o in your estimated regression function. Does b o provide any relevant information here? Explain. (d) Obtain a point estimate of the mean service time when X = 5 copiers are serviced. Use R programming .

1. MUST USE SPSS AND POST RESULTS. A researcher is interested in studying the effect that the amount of fat in the diet and amount of exercise has on the mental acuity of middle-aged women. The researcher used three different treatment levels for the diet and two levels for the exercise. The results of the acuity test for the subjects in the different treatment levels are shown below.

1. Perform a Two-way analysis of variance (ANOVA) and report the results using correct APA style; report whether significance was found for Factor A, Factor B, and/or an interaction between Factors A and B was found.
2. If the test statistic is significant, run a post hoc test to determine between what groups significance was found.
3. Report an effect size for all significant results.

Write a program that will calculate the sum of the first n odd integers, and the

sum of the first n even integers.

Use a Do while loop

Use a for loop

Here is a sample of how the program should run:

How many odd integers would you like to add? 5

Count Odd Integer Sum

1 1 1

2 3 4

3 5 9

4 7 16

5 9 25

The sum of the first 5 odd integers is 25

How many even integers would you like to add? 7

Count Even Integer Sum

1 2 2

2 4 6

3 6 12

4 8 20

5 10 30

6 12 42

7 14 56

The sum of the first 7 even integers is 56

Do you want to add again? Press y or n

y

How many odd integers would you like to add?

Make sure your program works with any input value from 1 to 1000.

REMEMBER! The sum of the first 5 odd integers is 1 + 3 + 5 + 7 + 9. It is NOT the

sum of the odd integers up to 5

Scenario: There is a box containing 4 different type color of balls green, blue, white and black there are total 20 balls in the box the number of different colored balls are given below: green - only 1 ball blue - 4 balls white - 8 balls black - 7 balls If you want to get a chance to select a ball from the box you must pay $2 and it will not get back if you win or loss. Each ball color wins different type of amount. The amount that are given to the player if he selects

green =$20 blue =$3 white =$1 black =$0

Would you play the game if; Probability of getting green ball=1/20

Probability of getting blue ball =4/20

Probability of getting white ball =8/20

Probability of getting black ball =7/20

Change that comes into our amount after selecting a ball is given if Select a green ball = $20-$2= $18 Select a blue ball = $3-$2 =$1 Select a white ball =$1-$2 = -$1 Select a black ball =$0-$2= -$2 Hence, Expected value is: = (1/20*18) +(4/20*1) +(8/20*-1) +(7/20* -2) = (18/20) +(4/20) +( -8/20) +( -14/20) = (18+4 -8 -14)/20 = (22 -22)/20 =0/20 = 0

We got an expected value of 0, meaning that the game is a fair game. Here we got expected value exactly 0 means neither profit nor loss if we are looking forward for the profit we should get an expected value more than 0. If we get an expected value 0.05, this means we have a profit of 0.05 on each try.

QUESTION= What is the THEORETICAL RESULTS and how does your experimental probability distribution results compare to them. Were they close? If they weren't close, what are some possible reasons why?

By experimenting with throwing 4 coins, find the following possibilities

1. What is the probability that the image will appear 3 times at most?

2. What is the probability that the image will appear at least 2 times?

3. What is the probability that the image will appear 1 times at most?

4. What is the probability of the image appearing more than three times?

5. What is the probability that the image will appear at least 3 times?

6. How likely is it to appear 4 times?

7. What is the probability that the image will appear 3 times?

8. What is the probability that the image will not appear?

9. What is the probability that the image will appear between 2 and 4?

10. What is the probability that all results will appear as pictures?
