Pleаse print Test 2 MAT137 Test 2-MAKEUP (Chаpter 2)- Spring 2023 .pdf If yоu dо nоt hаve access to a printer, neatly copy problems on paper and complete them. When you are finish, scan and upload your test paper along with your scratch paper using the upload/choose file link provided below. Do not end your Honorlock session until you have uploaded your test paper. A cellphone may be used to scan your test/scratch paper only after all problems are completed. Having out or using a cellphone/electronic device (other than an approved calculator) while taking the test is considered cheating. Appropriate action will be taken if this occurs.
Cоnsider а study оf Mаth scоres (Mаth) for n=14 students with information about their undergraduate major (Major) and weekly hours of study (Hours). The goal was to fit a regression model to express the dependence of Y (Math) on X (Hours) and Major (Engineering, History, or Science). Type your answers to the following questions in the text box below making sure to reference the relevant Minitab output in your answers. (5 pts) Clearly define a set of indicator variables that could be used in a regression model to represent the qualitative variable Major. [Hint: Think carefully about the number of indicator variables needed given the number of levels of Major and use "Engineering" as the reference level.] (5 pts) Write a population multiple linear regression equation for predicting the Math scores in terms of Hours and Major. Since Major could impact the dependence of Math score (Y) on Hours (X), include in the model interaction effects between Hours and Major, together with their main effects. [Hint: Your equation should include Y, X, the indicator variables you defined in part (a), interaction terms, and population regression coefficients (β’s). Do not include estimated coefficients, i.e., numbers, in this part.] (8 pts) Conduct a single hypothesis test based on the model from part (b) to determine whether the average change in Math score per one additional Hour of study per week differs by Major. Write the null and alternative hypotheses, the test statistic, the p-value, and the conclusion based on a significance level of 0.05. Use relevant parts of the following Minitab output to support your answer. [Not all the output is relevant.] (8 pts) Write a new population regression model based on your conclusion to part (c). Then conduct two separate hypothesis tests based on this new model for whether the mean Math score for a fixed number of Hours of study per week differs by Major. For each test, write the null and alternative hypotheses, the test statistic, the p-value, and the conclusion based on a significance level of 0.05. Use relevant parts of the following Minitab output to support your answer. [Not all the output is relevant.] (6 pts) Based on your conclusion to part (d), write three fitted regression equations that can be used to predict the Math score from the Hours of study per week for each Major. [Hint: Your equations should include number values, not β’s.] (4 pts) Based on one of the equations from part (e), predict the Math score for a History major who studies 4 hours a week. A point estimate is sufficient.
