Project Assignment Part 1For 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 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.Project Assignment Part 2For 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 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.Project Assignment Part 3For 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: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: β1 = 0oHa: β1 ≠ 0Write 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.Project Assignment Part 4Write a minimum 4 page report explaining the results from your analysis of the ROI of Business 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

School Assignment: In 1,250-1,500 words, answer the following questions about possible research options. 1.Create a research question in the field of psychology that you are interested in researching. Write questions clearly. Include a brief background of the problem you are proposing and why it is important to the field of psychology. 2.State the null and alternative hypothesis (in both words and statistical notation) need to address the research question. 3.Choose which statistical test would be used to conduct the study and support it with research. 4.Describe the type of data needs to be collected to conduct the study and what techniques are best for collecting data. Use three to five scholarly resources to support your explanations. Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required. This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.----------------My assignment question I want to focus is: Why understanding people’s emotions, their behavior and motivations is important to understanding their motives and why they do the things they do and the choices they make. Generally speaking, psychology is the study of understanding people’s behaviors and emotions.

It is required to complete a real-world application project. attached file.Choose either problem 46 or problem 48 on page 250. For the problem you choose, answer the following, showing your calculations: (a) Determine the vertex and interpret the meaning of (h, k) in the problem situation. (6pts) (b) Determine the x- and y-intercepts of the function. Interpret the meaning of each in the problem situation. Are all intercepts meaningful to the given problem? Explain. (6pts) (c) Many real-world applications have a restricted domain and range. Determine an appropriate domain and range for the problem you chose.
