Description
Discussion
There are three approaches to finding probability that you will discuss in this unit; theoretical probability, relative frequency probability, and subjective probability.- From your own experience either personally or professionally, provide an example of when you have encountered or used theoretical probability. Describe the example and explain why it is theoretical probability.
- From your own experience either personally or professionally, provide an example of when you have encountered or used relative frequency probability. Describe the example and explain why it is relative frequency probability.
- From your own experience either personally or professionally, provide an example of when you have encountered or used subjective probability. Describe the example and explain why it is subjective probability.

MAT 510 Strayer University Business Statistics Worksheet
This is assignment is due December 6, 2021. Linear Regression AnalysisTerry Downes owns a commercial cleaning company. He has conducted a survey of customers to determine how satisfied they are with the work performed. He devised a 100-point rating scale—with 0 being poor and 100 being excellent service, selected a random sample of 16 customers, and asked them to rate the service. He also recorded the number of worker hours spent in the customer's facility. These are in the file named Downes. Use Excel to complete the following:Develop a scatter plot showing the variables, rate of service, and worker hours, with the y variable on the vertical axis and the x variable on the horizontal.Develop a linear regression model to explain the variation in the service rating using a significant level alpha = 0.10Estimate the regression equation for the model.Use Word to complete a short report to include the following:The scatter plot describing the relationship of the variables and the estimated linear regression equation.The null and alternative hypotheses at the significant level alpha = 0.10The regression analysis showing the results of the pertinent hypothesis test, using a significance level of 0.10.The analysis of the linear regression indicating if the model is significant based on the p-value, e.g., rejecting or failing to reject the null hypothesis.The significance of the R2 (Coefficient of determination) in the model.Note: Submit your work in a Word document and attach your Excel file.By submitting this paper, you agree: (1) that you are submitting your paper to be used and stored as part of the SafeAssign™ services in accordance with the Blackboard Privacy Policy; (2) that your institution may use your paper in accordance with your institution's policies; and (3) that your use of SafeAssign will be without recourse against Blackboard Inc. and its affiliates.

MAT 240 SNHU Hypothesis Testing for Regional Real Estate Company Report
Listen
ReadSpeaker webReader: Listen
ScenarioYou have been hired by the Regional Real Estate Company to help them
analyze real estate data. One of the company’s Pacific region
salespeople just returned to the office with a newly designed
advertisement. It states that the average cost per square foot of his
home sales is above the average cost per square foot in the Pacific
region. He wants you to make sure he can make that statement before
approving the use of the advertisement. The average cost per square foot
of his home sales is $275. In order to test his claim, you collect a
sample of 1,001 home sales for the Pacific region.PromptDesign a hypothesis test and interpret the results using significance level α = .05.Use the House Listing Price by Region document to help support your work on this assignment. You may also use the Descriptive Statistics in Excel and Creating Histograms in Excel tutorials for support.Specifically, you must address the following rubric criteria, using the Module Five Assignment Template.Setup: Define your population parameter, including hypothesis statements, and specify the appropriate test.
Define your population parameter.Write the null and alternative hypotheses. Note: Remember, the salesperson believes that his sales are higher.Specify the name of the test you will use.
Identify whether it is a left-tailed, right-tailed, or two-tailed test.
Identify your significance level.
Data Analysis Preparations: Describe sample summary
statistics, provide a histogram and summary, check assumptions, and
find the test statistic and significance level.
Provide the descriptive statistics (sample size, mean, median, and standard deviation).Provide a histogram of your sample.Describe your sample by writing a sentence describing the shape, center, and spread of your sample.Determine whether the conditions to perform your identified test have been met.
Calculations: Calculate the p value, describe the p
value and test statistic in regard to the normal curve graph, discuss
how the p value relates to the significance level, and compare the p
value to the significance level to reject or fail to reject the null
hypothesis.
Determine the appropriate test statistic, then calculate the test statistic.Note:
This calculation is (mean – target)/standard error. In this case, the
mean is your regional mean (Pacific), and the target is 275.Calculate the p value.Note: For
right-tailed, use the T.DIST.RT function in Excel, left-tailed is the
T.DIST function, and two-tailed is the T.DIST.2T function. The degree of
freedom is calculated by subtracting 1 from your sample size.Choose your test from the following:=T.DIST.RT([test statistic], [degree of freedom])=T.DIST([test statistic], [degree of freedom], 1)=T.DIST.2T([test statistic], [degree of freedom])Using the normal curve graph as a reference, describe where the p value and test statistic would be placed.
Test Decision: Discuss the relationship between the
p value and the significance level, including a comparison between the
two, and decide to reject or fail to reject the null hypothesis.
Discuss how the p value relates to the significance level.Compare the p value and significance level, and make a decision to reject or fail to reject the null hypothesis.
Conclusion: Discuss how your test relates to the hypothesis and discuss the statistical significance.Explain in one paragraph how your test decision relates to your hypothesis and whether your conclusions are statistically significant
