MA215 Grantham Week 7 ROI Data Coefficient of Determination Project
Project Week 7For these project assignments throughout the course you will need to reference the data in the ROI Excel spreadsheet. Download it here.
Using the ROI data set:For each of the two majors:Create a scatter diagram of Y = ‘Annual % ROI’ against X = ‘Cost’. Include the trendline, the equation of the trendline, and the coefficient of determination on the graph.Obtain b0 and b1 of the regression equation defined as y ̂ = b0 + b1X. Hint from Dr. Klotz: You can get this right from the trendline.Calculate the estimated ‘Annual % ROI’ when the ‘Cost’ (X) is $160,000.Conduct a full hypothesis test: You will be in charge. Set your own significance level. The hypotheses are given.H0: β1 = 0Ha: β1 ≠ 0Hint: Remember that a full hypothesis test is more than running the data analysis program. What were the steps from last week's discussion?In a highlighted box, discuss your final conclusion from this hypothesis test. For each major, is Annual % ROI related to Cost for business? For engineering? If so, describe the relationship in words. How does the outcome of this hypothesis test related to the central question of which ROI is better?

Question that we talked about.
Mary is planning a study to see if learning of 6th graders on a math
lesson is affected by background noise level. She wants to use a t-test
for independent groups to analyze her results. Help her plan her study.
What is her independent variable (IV) here? Describe two conditions she
could create for the IV in her study. What is her dependent variable
(DV) here? Describe a way to measure the DV so that each participant
would have one score at the end. Would this DV measure be on a
continuous scale of measurement? Why is this important? Explain and

Easy Statistics Project Confidence Pricing Interval Exercise
The B&K Real Estate Company sells homes and is currently serving the Southeast region. It has recently expanded to cover the Northeast states. The B&K realtors are excited to now cover the entire East Coast and are working to prepare their southern agents to expand their reach to the Northeast.
B&K has hired your company to analyze the Northeast home listing prices in order to give information to their agents about the mean listing price at 95% confidence. Your company offers two analysis packages: one based on a sample size of 100 listings, and another based on a sample size of 1,000 listings. Because there is an additional cost for data collection, your company charges more for the package with 1,000 listings than for the package with 100 listings.
SAMPLE SIZE OF 100 LISTINGS:
95% confidence interval for the mean of the Northeast house listing price has a margin of error of $25,000
Cost for service to B&K: $2,000
SAMPLE SIZE OF 1,000 LISTINGS:
95% confidence interval for the mean of the Northeast house listing price has a margin of error of $5,000
Cost for service to B&K: $10,000
The B&K management team does not understand the tradeoff between confidence level, sample size, and margin of error. B&K would like you to come back with your recommendation of the sample size that would provide the sales agents with the best understanding of northeast home prices at the lowest cost for service to B&K.
In other words, which option is preferable?
Spending more on data collection and having a smaller margin of error
Spending less on data collection and having a larger margin of error
Choosing an option somewhere in the middle
For your initial post:
Formulate a recommendation and write a confidence statement in the context of this scenario. For the purposes of writing your confidence statement, assume the sample mean house listing price is $310,000 for both packages. “I am [#] % confident the true mean . . . [in context].”
Explain the factors that went into your recommendation, including a discussion of the margin of error
