MIS445 Colorado State Google and Amazon Stock Return Analysis
In this CT assignment, we will use R software to analyze a dataset GoogleAmazonStock.xlsx.It contains daily closing stock prices for Google and Amazon from 8/22/2017 to 8/22/2018. When we examine stock prices (or other financial assets) we often transform them into a (simple) return series. The return series are computed by the formula: (present price/past price) - 1. The dataset contains both stock prices and return series.1. Using R, construct time series (line) plots for both stock prices and return series. R functions ts.plot or plot can create the plot. Describe the patterns and compare the plots. 2. Based on the return series, can we claim that the mean Amazon return series is higher than that of Google?a. What would be an appropriate test of the claim above? Explain. b. Write the null and alternative hypotheses. c. Using R, perform the test. d. Write the decision in the problem context.Take the screenshots of the R graphs and output as well as the code. Paste them into a Word document along with your answers to the questions above. Clearly label the questions and answers. Submit the Word file in Canvas.

Need to have the two papers Article 1 and Article 2 on two different topics Article Reviews
You will write a 2 page review/abstract/summary on an article from a peerreviewed scholarly journal. This is to assess your ability to select and summarize
the research of others, analyze and apply the research of others, and communicate
professionally and effectively to their regard. However, the most important
rationale for this assignment is for you to see how statistical analysis is presented.
Instructions:
1. Use the library system (https://www.ucumberlands.edu/library) or online catalog to
locate a journal article that pertains to your research, thesis, or area of
interest. The article you chose should have performed some statistical
analysis of gathered data and made an inference using something other than
just the average (mean). That is, they can’t just talk about averages; they
must have used one of these tests: t-test, chi-square, F-test, Fischer test,
ANOVA, MANOVA, ANCOVA, Mann-Whitney, correlation, regression.
2. Read the article thoroughly.
3. Write a 2-page summary about the article following the given guidelines.
Guidelines:
1. Your review should include:
a. The question/problem being researched by the author
b. The experiment that will answer the question
c. How they collected data
d. Analysis of the data (Must identify the statistical test used)
e. Their conclusion or findings
2. Your review can be single spaced or double spaced in at least 11 pt font.
3. You should make a bibliography to list the article you chose and practice APA
format. NOTE: The APA Guidelines address specifically how the reference
page is title and how articles are provided! Note: It is not called Bibliography.
4. Graphs or visual representations are not needed for this assignment.
5. A title page is not required, but you may include one if you want to practice
APA style. If you have a title page, your submission is 4 pages. If you do not
have a title page, your submission is 3 pages. Do not go over. There are
points associated with following the directions.
6. Your grade on these assignments will be based on the rubric below. FOLLOW
THESE GUIDELINES.

Business Profits
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 dollars2016 Profit in millions of dollars2015-2016 Two-Year Change in Daily Average Customer Visits Two-Year Average Number of EmployeesData collected for the sample of 200 businesses is contained in the file named Businesses, linked at the bottom of the page. Use all 200 data points.Managerial ReportPrepare 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 business. Be sure to include the following three items in your report.Find descriptive sample statistics (mean, median, two quartiles Q1 and Q3, minimum, maximum, 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.Compute the percent change in profit from 2015 to 2016 for each business. Then use the z-score to determine which businesses were outliers with respect to percent change in profit.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.
