A comparative balance sheet for Lomax Company containing data for the last two years is as follows:

The following additional information is available about the company’s activities during this year:

1. The company declared and paid a cash dividend this year.

2. Bonds with a principal balance of $400,000 were repaid during this year.

3. Equipment was sold during this year for $80,000. The equipment had cost $170,000 and had $64,000 in accumulated depreciation on the date of sale.

4. Long-term investments were sold during the year for $150,000. These investments had cost $68,000 when purchased several years ago.

5. The subsidiaries did not repay any outstanding loans during the year.

6. Lomax did not repurchase any of its own stock during the year.

The company reported net income this year as follows:

Required:

Using the indirect method, prepare a statement of cash flows for this year. (List any deduction in cash outflows as negative amounts.)

A computer is programmed to produce at random a single digit from the list 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The program is run 8 times. Let Y be the number zeros that occur.i)

If Yfollows the Binomial Distributions, state two assumptions for this.

i)Calculate the values of theparameters.

ii)Calculate P(Y<4)

Let X be the number of goal chances that result in goals for a football team over n goals chances. During many matches, the team gets goals of 20% of the chances.

a) Explain why it might be reasonable (at least as an approach) to assume that X is binomially distributed in this situation. Do this by going through each of the points that must be met in order for us to use binomial distribution, assess whether it is reasonable that they are met here, and specify any additional assumptions we need to make. solved

Not solved:

What is the probability that the team gets two goals in a match with n = 12 goal chances?
What is the probability that they will get more than 50 targets in a season if they get n = 300 target chances?

Before a new season acquires two new spikes in hopes of increasing the likelihood of scoring on the target chances. During the first 116 goals they received 29 goals.
b) Determine with a hypothesis test whether the probability of scoring on the target chances has increased. Use 5% level. Also calculate the p-value of the test.
What would have been the conclusion of the test if we had used a 10% level?

I want to see if there is a relation between makeup sales and the age of people buying them on any given day at Sephora. 10 people were randomly sampled.

X-axis: 13, 14, 16, 17, 21, 25, 30, 37, 50, 62 (age)

Y-axis: 2, 7, 30, 26, 15, 33, 7, 3, 14, 1 (Makeup sales)

What is the impact of using a linear regression model in this case? What options, other than linear regression, can you see? You do not need to collect any data.

For your response to a classmate (two responses required, one in each option), examine your classmate’s problem to assess the appropriateness and accuracy of using a linear regression model. Discuss the meaning of the standard error of the estimate and how it affects the predicted values of Y for that analysis.

A) 1 Formulate two postulates of the Einstein’s special theory of relativity.

2 According to the special theory of relativity, if you are in a train that moves at nearly the speed of light what would you see if you look into a mirror? Explain your answer.

A study of the effect of television commercials on 12-year-old children measured their attention span, in seconds. The commercials were for clothes, food, and toys.

1.) Complete the ANOVA table. Use 0.05 significance level. (Round the SS and MS values to 1 decimal place and F value to 2 decimal places.)

2. Find the values of mean and standard deviation. (Round the mean and standard deviation values to 3 decimal places.)

3.) Is there a difference in the mean attention span of the children for the various commercials?

The hypothesis of identical means can definitely REJECTED/ NOT REJECTED be.There is A DİFFERENCE /NO DİFFERENCE in the mean attention span.

Purpose:To begin investigating the FAT16 file system on a USB memory device. In particular, you will add a file to a FAT16 formatted device and observe the changes made to the FAT table.

Deliverables: For Steps 7, 8, 11, and 12 you are to describe, in detail, what happens to the FAT when a file is added. Be specific and explain WHAT happened and WHY. It is acceptable to add small screen shots to you DOC file, but only as an aid in describing your observations.

Activities:

1. Use a USB flash drive that contains NO data that you need.
   1. You will want this flash drive to be as small as possible!
   2. Really! You want this to be as small as possible.
2. Format the drive with the FAT16 file system.
   1. During the format process name your drive “YourName-1a”
3. Using FTK Imager add this device as an evidence item.
4. Select FAT1 and do a screen shot of the Hex View window.
5. Close FTK Imager.
6. Add a small text file to the root directory of the Flash drive.
7. Using FTK Imager add this device as an evidence item.
   1. Find FAT1 and do a screen shot of the Hex View window.
   2. Compare the 2 screen shots and write down the chain of sectors that contain the text file.
8. Select the text file in the File List window.
   1. Look at the Status Bar and identify the sector number.
   2. Compare that cluster number to the Cluster Chain. They should match (+1 offset) If they don’t match, repeat the process starting at step 7 to identify your problem.
9. Close FTK Imager
10. Add a medium sized image file to the root directory of the Flash drive.
11. Using FTK Imager add this device as an evidence item.
    1. Find FAT1 and do a screen shot of the Hex View window.
    2. Compare the 2 screen shots and write down the chain of sectors that contain the image file.
12. Select the image file in the File List window.
    1. Look at the Status Bar and identify the sector number.
    2. Compare that cluster number to the Cluster Chain. They should match (+1 offset) If they don’t match, repeat the process starting at step 7 to identify your problem.
13. Close FTK Imager

8. The Kansas Department of Social Services is facing a complaint that minority social workers are given different (namely lower) starting salaries than white/Caucasian workers. As a local social worker support organization, you conduct a survey of 19 caseworkers asking their monthly caseload for May 2016 shown below with 10 minority and 9 white/Caucasian workers. Data in thousands of dollars.

minority 50, 40, 52, 40, 45, 40, 35, 55, 45, 40

white/Caucasian workers 25, 30, 30, 40, 50, 25, 40, 35, 41

a) Provide null and alternative hypotheses in formal terms and layperson's terms for the test (5)

b) Do and show the math and reject/accept at a=.05 (10)

d) Explain the results in layperson's terms (10)

e) Calculate and then explain a 95% confidence interval in layperson's terms if appropriate. If not, you must explain why not. (10)
