Business Statistics Assignment
Business Statistics Project Assignment
Write a minimum 4-page report explaining the results from your analysis of the ROI of Busine ss Majors and Engineering Majors. Use your results from each week’s assignment to make this report.
This report should include:
A detailed description of the data used in this analysis – specifically explain what the data in each column represents.
A detailed explanation of any information learned about:
School Type for each major;
The Cost for each major;
The 30 Year ROI for each major;
The Annual % ROI for each major.
Explanations should be supported with the results obtained from your work in previous weeks.
Finally, answer the following questions and support your answer with your results.
Does there appear to be a particular major that gives a better ROI? Why or Why not?
Given that we are using statistical inference to make our conclusions, is it guaranteed that the major you choose that gave a better ROI for this sample will always have a better ROI than the other major? Explain your reasoning.
**Below are the questions that were answered for each assignment.Also, attached are my weeks of ROI (results from each week’s assignment) and the ROI Excel spreadsheet used for each assignment.**
Attachment 1
For these project assignments throughout the course you will need to reference the data in the ROI Excel spreadsheet.
In this data set – the ROI data set - for 2 different majors (Business and Engineering), you are given a sample of the 20 best colleges according to ROI (ROI = Return on Investment) and their ‘School Type’, ‘Cost’, ’30-Year ROI’, and ‘Annual % ROI’.
For each of the 2 majors create a pie chart using the column ‘School Type’. Comment on your results.
For each of the 2 majors create a frequency distribution and histogram using the column ‘Annual % ROI’. Group with starting at 6% (0.06), ending at 11% (0.11), and go by 0.5% (0.005).
For the histograms title your charts “Histogram Business Major: Annual % ROI” for Business majors and “Histogram Engineering Major: Annual % ROI” for Engineering Majors. Comment on your results.
Attachment 2
For each of the 2 majors calculate the mean, median, minimum, maximum, range, and standard deviation for the columns ‘Cost’ and ’30-Year ROI’.
By hand or with Excel, for each of the 2 majors calculate the probability that a college picked from the column for ‘School Type’ is ‘Private’.
By hand or with Excel, for each of the 2 majors find the probability that a college with the ‘School Type’ ‘Private’ has a ’30-Year ROI’ between $1,500,000 and $1,800,000.
Attachment 3
If we select 7 colleges from a major and then record whether they are of ‘School Type’ ‘Private’ or not, is this experiment a binomial one? Why or why not?
For each of the 2 majors determine if the ‘Annual % ROI’ appears to be normally distributed. Consider the shape of the histogram and the measures of central tendency (mean and median) to justify your results. Report on each of these with charts and calculations to justify your answers.
Attachment 4
For each of the 2 majors consider the ‘School Type’ column. Assuming the requirements are met, construct a 90% confidence interval for the proportion of the schools that are ‘Private’. Be sure to interpret your results.
For each of the 2 majors construct a 95% confidence interval for the mean of the column ‘Annual % ROI’. Be sure to interpret your results.
Attachment 5
For each of the 2 majors test the hypothesis at the 5% significance level:
The mean ‘Cost’ for a college is $160,000. Be sure to interpret your results.
For Business versus Engineering majors conduct a two sample test of the hypothesis at the 10% significance level (assume the variances are not equal):
The average ’30-Year ROI’ for Business majors is less than for Engineering Majors. Be sure to interpret your results
Attachment 6
Using the ROI data set:
For each of the two majors:
Draw the scatter diagram of Y = ‘Annual % ROI’ against X = ‘Cost’.
Obtain b0 and b1 of the regression equation defined as y ? = b0 + b1X and the coefficient of determination (r2) from the Excel regression output.
Draw the fitted regression line on the scatter diagram.
Calculate the estimated ‘Annual % ROI’ when the ‘Cost’ (X) is $160,000.
Test the hypothesis:
oH0: ?1 = 0
oHa: ?1 ? 0
Write a paragraph or more on any observations you make about the regression estimates, coefficient of determination, the plots, and the results of your hypothesis tests.
Please provide original work.No plagarizing.If you have any questions please let me know.

Maricopa Community Colleges Statistics Questions
A social worker notes that in a population of psychiatric inpatients the ethnic mix seems out of balance with what she has understood to be the ratios in the general population. Respond to the prompts below to show how she might determine whether the inpatient ethnic mix varies from the mix in the general population. (1 point each)
What statistical test would be appropriate to use here? Explain the rationale for your answer.
What assumptions would need to be met in order to use the test?
Describe the data that the test would be based on as either quantitative or qualitative. Explain the rationale for your answer.
Write an example of how the null and alternative hypotheses for this test could be stated.
What would the researcher need to know in order to calculate the appropriate test statistic? I.e., what values need to be known or calculated in order to complete the calculation of the test statistic?
Given a data set that can be graphed as a standard normal curve, respond to the prompts below. (1 point each)
What defines the graph? I.e., what determines the shape of the graph and what is the relationship between these defining characteristics?
What must be done in order to transform a normal distribution of data into a standard normal distribution based on the same data?
What is the advantage of having transformed data so that it can be represented by a standard normal distribution?
We often see data points represented by either x or z. What is the relationship between them?
Why is the area under the standard normal curve above the mean always the same value?
A school psychologist wants to determine whether children who live with both parents perform better on school work than children who live with a single parent. She gathers two groups for her comparison, 20 children who live with both parents and another 20 who live with a single parent. The psychologist plans to use scores on a standardized achievement test as an indicator of school performance. Respond to the prompts below.
What statistical test would be appropriate in this case? Explain the rationale for your answer.
Identify the independent variable in this study.
Identify the dependent variable in this study.
Describe a potentially confounding variable and explain how that might affect the conclusions from the study.
State the null and alternative hypotheses in words.
A team of psychologists have developed an experimental treatment program for a learning disorder with the expectation that the treatment would enable recipients to score higher than before on a test of learning ability. To test the treatment, they randomly select a pool of 30 volunteers who have been diagnosed with the disorder and who have volunteered for the treatment program. Following treatment, the participants are retested on the learning ability test and their scores compared to earlier scores. Complete the following.
What statistical test would be appropriate in this case? Explain the rationale for your answer.
State the null and alternative hypotheses in words.
State the null and alternative hypotheses in statistical symbols
Would the test be right-tailed, left-tailed or two-tailed? Explain the rationale for your answer.
Describe a potentially confounding variable and explain how that might affect the conclusions from the study.Describe a potentially confounding variable and explain how that might affect the conclusions from the study.
A social psychology professor is interested in determining whether cell phone use while driving is related to having received a speeding violation. Complete the following.
What statistical test would be appropriate to use? Explain the rationale for your answer.
Suggest how levels of these variables might be arranged in a table.
Write an example of how the null and alternative hypotheses for this test could be stated.
Is the statistical test right-tailed, left-tailed or two-tailed? Explain the rationale for your answer.
Assuming a statistically significant outcome, write a statement summarizing the conclusion.
