     You are to put together a PowerPoint presentation that explains the analysis of your findings which you will submit to your manager. The presentation should contain all components of your findings. For review, the components of the report should include: 
   1. Brief overview of the scenario and variables in the data set
   2. Discussion, calculation, and interpretation of the mean, median, mode, range, standard deviation, and variance
   3. Discussion, construction, and interpretation of the 95% confidence interval
   4. Explanation of the full hypothesis test
   5. Conclusion

Please work out the problems attached can send back in a word document please. Please show work so I can understand. this is Graphing Quadratic Functions.

I’m working on a algebra multi-part question and need an explanation and answer to help me learn.

(The first few questions have been already answered for understanding, please see the attached image for the actual questions)

1. The Anderson family consists of married couple Hannah and Jonathan, and their young daughter Eva. Hannah is a software designer making $58,000 per year, and Jonathan is an office manager making $46,000 per year.

(a). Should they file their taxes jointly or seperately?

Jointly: $9,039

Separately: $9,509
They should file jointly

(b). Determine the FICA taxes for both Hannah and Jonathan.

Hannah:

Social Security tax: $3,596

Medicare Tax: $841

Jonathan:

Social Security tax: $2,852

Medicare Tax: $667

Medicare tax if filed jointly: $1,508

Social security tax if filed jointly: $6,448

In this assignment, you will create a PowerPoint presentation that details a number of quantitative analysis methods and indicates how and when they should be used to solve business problems.

PowerPoint presentation including an analysis of 8 different methods and a practical example of a business problem.

Each analysis should be addressed on one slide, and must include:

The title of slide should be the name of the method being discussed.

1. A small description of the method (must be cited)

The type of problem it can be used to solve or example of the method in use.

• Each slide must have at least one citation
• All information must be on slide, nothing in the notes section of the PowerPoint.
• Practical example
• invent a business problem, and briefly describe it in one slide
• create a simple decision tree to select the quantitative method used to evaluate it

include a sample evaluation and recommendation for the business problem.

Hypothesis testing is used in business to test assumptions and theories. These assumptions are tested against evidence provided by actual, observed data. A statistical hypothesis is a statement about the value of a population parameter that we are interested in. Hypothesis testing is a process followed to arrive at a decision between 2 competing, mutually exclusive, collective exhaustive statements about the parameter’s value.

Consider the following scenario: An industrial seller of grass seeds packages its product in 50-pound bags. A customer has recently filed a complained alleging that the bags are underfilled. A production manager randomly samples a batch and measures the following weights:

Weight, (lbs)

45.6 49.5

47.7 46.7

47.6 48.8

50.5 48.6

50.2 51.5

46.9 50.2

47.8 49.9

49.3 49.8

53.1 49.3

49.5 50.1

To determine whether the bags are indeed being underfilled by the machinery, the manager must conduct a test of mean with a significance level α = 0.05.

In a minimum of 175 words, respond to the following:

• State appropriate null (Ho) and alternative (H1) hypotheses.
• What is the critical value if we work with a significant level α = 0.05?
• What is the decision rule?
• Calculate the test statistic.
• Are the bags indeed being underfilled?
• Should machinery be recalibrated?

The purpose of this project is to have you complete all of the steps of a real-world linear regression research project starting with developing a research question, then completing a comprehensive statistical analysis, and ending with summarizing the reseach conclusion.

Attached are the guideline and rubric along with the supporting documents.

Full question list will be released at 3pm gmt today (26th May). There will be 4 questions, and they will be very similar to the example questions attahced below. I will upload them just after 3pm gmt, and would like the answers sent to me before 5pm gmt.

g(x) 7x 2 = − ,
a. Verify: g(x + 2) ≠ g(x) + g(2).
b. Find (f – g)(x).
c. Using the resulting function in (b), show that (f – g)(2) = f(2) – g(2).
