I will need the initial question answered before the deadline

Please complete the initial discussion board and reply to 2 classmates- APA format

after you submit the initial post I will give you the classmates post and you will respond to the 2.

The research firm LL Research collected data from 200 client businesses. They want to determine how the businesses compare among four variables:

2015 Profit in millions of dollars
2016 Profit in millions of dollars
2015-2016 Two-Year Change in Daily Average Customer Visits

Two-Year Average Number of Employees

Data collected for the sample of 200 businesses is contained in the file named Businesses. Be sure to use all 200 data points.

Managerial Report
Prepare a report (see below) using the numerical methods of descriptive statistics presented in this module to learn how each of the variables contributes to the success of a client’s business. Be sure to include the following three items in your report.

Compute descriptive sample statistics (mean, median, two quartiles Q1 and Q3 (using QUARTILE.EXC), minimum, maximum, range, interquartile range, sample standard deviation, and coefficient of variation) for each of the four variables along with an explanation of what the descriptive statistics tell us about the client businesses.

In this case, which measure of central tendency would be best for this application? Explain why.

Which measure of variation would be best for this application? Explain why.

How can one use the above descriptive statistics to understand the businesses better?

Which graphical displays of data would you use to help understand or complement the above descriptive statistics? Explain how and why.

Note: QUARTILE.EXC works only for Excel 2010 or newer.

Compute the percent change in profit from 2015 to 2016 for each business.

What would the percent change tell us in this application?

Then use the z-score to determine which businesses were outliers with respect to percent change in profit.

1. How would identifying outliers be useful in this application?

What advice might you give to businesses that are outliers?

• How else would you determine outliers?
• Compute the sample correlation coefficient, showing the relationship between percent change in profit and each of the other two variables (2015-2016 Two-Year Change in Daily Average Customer Visits and Two-Year Average Number of Employees).
• Explain what the correlation coefficients tell us about the three pairs of relationships. Use tables, charts, or graphs to support your conclusions. 

I’m working on a Geometry question and need guidance to help me study.

Requires a simple easy to understand solution for the below mentioned question.

Show that, any plane whose normal lies on the curve (b + c)x² + (c + a)y² + (a + b)z² = 0 cuts the surface ax² + by² + cz²= 1 in a rectangular hyperbola.

I’m stuck on a Algebra question and need an explanation.

Required simplified solution of the below problem.

A and B are 2 ideals of ring R.

Show that A + B is an ideal generated by (A U B)

i.e. A + B = (AUB)

   A local law firm has hired G&B consulting to help determine a business strategy. There is a competing firm in the area and recently the two firms have begun talks in regards to a merger. The merger would mean there are more shared resources than either had before individually. There would also be less competition for both companies. Both would be able to operate more efficiently, however it would take a strong commitment from both sides for the merger to be successful. The law firm that has hired you wants to know their optimum strategy in this situation. 
2. Instructor feedback: the analysis that follows on #’s 2 and 3 is incorrect. Make sure that you are pointing out which values are being compared each step of the way, and explain the player’s preference by comparing the numbers in each case

All HW questions are summarized in the following file HW_2.html

These questions came from your book and they are converted as questions as part of this assignment. For some questions, you may provide a short answer by using the equation editor in Canvas. For some questions, you will need to upload a picture of your handwritten calculations. If you perform any calculations using R software, please take a screenshot of your R code and upload it to the question response box.

I’m working on a mathematics discussion question and need a sample draft to help me learn.

For this discussion, take a moment to reflect on the relationship between proofs and problem solving. What are some of the similarities in the approach to each? What are some of the differences?

Need help with my Statistics question – I’m studying for my class.

Scenario (information repeated for deliverable 01, 03, and 04)

A major client of your company is interested in the salary distributions of jobs in the state of Minnesota that range from $30,000 to $200,000 per year. As a Business Analyst, your boss asks you to research and analyze the salary distributions. You are given a spreadsheet that contains the following information:

• A listing of the jobs by title
• The salary (in dollars) for each job

In prior engagements, you have already explained to your client about the basic statistics and discussed the importance of constructing confidence intervals for the population mean. Your client says that he remembers a little bit about hypothesis testing, but he is a little fuzzy. He asks you to give him the full explanation of all steps in hypothesis testing and wants your conclusion about two claims concerning the average salary for all jobs in the state of Minnesota.

Background information on the Data

The data set in the spreadsheet consists of 364 records that you will be analyzing from the Bureau of Labor Statistics. The data set contains a listing of several jobs titles with yearly salaries ranging from approximately $30,000 to $200,000 for the state of Minnesota.

What to Submit

Your boss wants you to submit the spreadsheet with the completed calculations, answers, and analysis.

I’m trying to learn for my Probability class and I’m stuck. Can you help?

problem 1. Let x be a number chosen uniformly at random from [0, 1]. Find the probability of each of the
following events:

(a) 0.4 < x < 0.72;

(b) 0.4 ≤ x < 0.72;

(c) x ∈ {0.1, 0.2, 0.5, 0.7};

(d) x is one of the values in the infinite list 0.1, 0.11, 0.111, 0.1111, . . . ;

(e) x is a rational number.
