Scenario Background:
A marketing company based out of New York City is doing well and is looking to expand internationally. The CEO and VP of Operations decide to enlist the help of a consulting firm that you work for, to help collect data and analyze market trends.
https://www.mercer.com/insights/total-rewards/talent-mobility-insights/cost-of-living/#rankings
You work for Mercer Human Resources. The Mercer Human Resource Consulting website lists prices of certain items in selected cities around the world. They also report an overall cost-of-living index for each city compared to the costs of hundreds of items in New York City (NYC). For example, London at 88.33 is 11.67% less expensive than NYC.
More specifically, if you choose to explore the website further you will find a lot of fun and interesting data. You can explore the website more on your own after the course concludes.
https://mobilityexchange.mercer.com/Insights/ cost-of-living-rankings#rankings
Assignment Guidance:
In the Excel document, you will find the 2018 data for 17 cities in the data set Cost of Living. Included are the 2018 cost of living index, cost of a 3-bedroom apartment (per month), price of monthly transportation pass, price of a mid-range bottle of wine, price of a loaf of bread (1 lb.), the price of a gallon of milk and price for a 12 oz. cup of black coffee. All prices are in U.S. dollars.
You use this information to run a Multiple Linear Regression to predict Cost of living, along with calculating various descriiptive statistics. This is given in the Excel output (that is, the MLR has already been calculated. Your task is to interpret the data).
Based on this information, in which city should you open a second office in? You must justify your answer. If you want to recommend 2 or 3 different cities and rank them based on the data and your findings, this is fine as well.
Deliverable Requirements:
This should be ¾ to 1 page, no more than 1 single-spaced page in length, using 12-point Times New Roman font. You do not need to do any calculations, but you do need to pick a city to open a second location at and justify your answer based upon the provided results of the Multiple Linear Regression.
The format of this assignment will be an Executive Summary. Think of this assignment as the first page of a much longer report, known as an Executive Summary, that essentially summarizes your findings briefly and at a high level. This needs to be written up neatly and professionally. This would be something you would present at a board meeting in a corporate environment. If you are unsure of an Executive Summary, this resource can help with an overview. How to Write an Executive Summary That Gets the Job Done 2023.pdf
Things to Consider:
To help you make this decision here are some things to consider:
Based on the MLR output, what variable(s) is/are significant?
From the significant predictors, review the mean, median, min, max, Q1 and Q3 values?
It might be a good idea to compare these values to what the New York value is for that variable. Remember New York is the baseline as that is where headquarters are located.
Based on the descriiptive statistics, for the significant predictors, what city has the best potential?
What city or cities fall are below the median?
What city or cities are in the upper 3rd quartile?

Hi there , this is STAT 101 class and i am requesting the writer 325247 he/ she did my order. #545824358 on November 13 2023. so my order had 3 parts and he did the 3rd part wrong so i am requesting again for doing ONLY the 3rd part. Note – I uploaded a picture of my instructors feedback please correct it, Take the notes into consideration
PART 3 The Steps To Take:
When you have chosen your INTERVAL variable: Gather the frequency distribution for your variable and be sure you are using the numbers for the 2022 survey year. You will use the frequency distribution to find the mode, median, and range, when relevant. Remember to ignore any category that is for a “non” answer, e.g., don’t know, no answer, no response, etc. Be sure to note the names of the categories for your nominal and ordinal variables – they may be coded with numbers but those do not mean anything – use the names for each category! To get mean and standard deviation, please use this list. DO NOT CALCULATE THOSE YOURSELF. (You have too much to do right now and it’s not always possible, depending on which variable you chose.) Analyze only your INTERVAL variable in this part. If you would like more guidance on how to choose and deal with your variables, check out the examples tab. Use the outline to write up your analysis. There is no great need to include the frequency distributions – but if you do want to include them, put them in an appendix (optional). then have a paragraph describing your appropriate central tendency and variability statistical patterns for your variable in your own words. Use This Outline Interval Variable– Describe the distribution of your data for this variable. Interpret the frequency distribution and appropriate measure(s) of central tendency (Mean, Median, Mode, skew, best measure) and variability (Range, sd). Introduction – Tell us what your variable is, in everyday words and, briefly, why you chose it. Discussion: Description of the statistical patterns of central tendency and variability, in everyday words. Use ONLY the relevant statistics for the level of measurement. Please send it as a word pdf.INTERVAL variable. Please also check the list which I uploaded to get mean and standard deviation for the 3rd part of this assignment , please use the list given!! just like in the examples provided! please check the details list as well. if you have any question please contact me.

About: In this assignment, you will be looking at statistical output for the ANOVA. The objective is to apply your understanding of how the ANOVA and hypothesis testing works to tell us whether we have a significant relationship between our variables. You will analyze provided data and write a report explaining the populations, variables, which one is the independent and dependent variable, and the results of the ANOVA hypothesis test.
Directions: Select ONE scenarios provided after the directions and complete the following report for your scenario.
Introduction (100 words minimum)
Explain what the independent and dependent variable is in your scenario
Provide the Null and Research hypothesis as based on the two variables provided
Methods (50 words minimum)
Descriptive Statistics: describe the observable differences between the groups (in other words compare their means)
State and briefly explain the f-statistic results (F-statistic and p-value in particular)
NOTE: YOU DO NOT HAVE TO CALCULATE ANY VALUES, ALL VALUES ARE PROVIDED IN THE STATISTICAL OUTPUT
3. Results (100 words minimum)
Interpret the results by explaining where there is a statistically significant relationship or not.
Make sure to state whether we accept or reject the null hypothesis.
Make sure to explain whether this means the two variables are statistically related or not.
4. Discussion (100 words minimum)
Provide some thoughts and considerations on why we obtained the results
Consider at least two additional variables that can explain the results
Clearly and fully explain how the additional variables can affect the results
Word Count: Your report should be about 350 words minimum! Include your word count at the end of your post.

Assignment Deliverable
Complete the following on the Data tab of the Pastas R Us data file: The file is attached.
1) Calculate “Annual Sales” for each restaurant. Annual Sales is the result of multiplying a restaurant’s “SqFt.” by “Sales/SqFt.” The first value has been provided for you.
2) Calculate the mean, standard deviation, skew, 5-number summary, and interquartile range (IQR) for each of the variables. The formulas and the first results have been provided for you.
3) Create a boxplot (sometimes referred to as a box and whisker chart) for the “Annual Sales” variable.
4) Create a histogram for the “Sales/SqFt” variable.
Respond to the following questions on the Questions tab of the Pastas R Us data file:
1) Does the annual sales boxplot look symmetric?
2) Would you prefer the IQR instead of the standard deviation to describe the dispersion of the annual sales variable? If so, why?
3) Does the histogram show that the sales per square foot distribution is symmetric?
4) If the sales per square foot distribution is not symmetric, what is the skew?
5) If there are any outliers, which one(s)? What is the “SqFt” area of the outlier(s)?
6) Is the outlier(s) smaller or larger than the average restaurant in the data? What can you conclude from this observation?
7) What measure of central tendency may be more appropriate to describe “Sales/SqFt”? Why?

I have uploaded the Rubric/Guidelines, Module Overview, Reading and Resources, and chapters from the textbook.

I need help calculating statistical analysis for a psychology undergrad research paper. I need help with the analysis of 3 hypothesis with given data and survey items. The variables measured are the variables of 1)2 personality traits, 2)workaholism and 3) general sociodemographics. Scales used are BWAS(workaholism) and mini IPIP(Neuroticism and Concienciousness) all of which use liker scales.I would like the writer to apply the appropriate statistical methods such as ANOVA, T tests,Regression and correlation in order to examine my hypothesis, as well as do general descriiptives and provide me with a) an output of the results on SPSS b)the calculation methods used and why and c) given a very brief explanation of the results so I can understand them better. I would like the writer to only use the SPSS statistical software. Further information and files can be given to the writer if needed
