College leadership wants to make a simple linear regression model to predict astudent's final statistics grade based upon the class size that the student is enrolled in.
1).First make scatterplot using Class Size as the independent variable and Average Final Grade as the dependent variable.
2). After performing a visual analysis of thescatterplot, ifappropriate, construct a simple linear regression model using class size to predict astudent's final grade.
3). Using your simple linear regressionmodel, what is the value for the slope for this regressionmodel?Interpret the slope is this context.
4). What is the value for they-intercept for this regressionmodel?Interpret they-intercept in this context.
5) College leadership is interested in forecasting astudent's final grade based upon the class size of the statistics course. Using your simple linear regressionmodel, what is the predicted Average Final Grade of a statistics class when the Class Size is 35?
6).Based upon your simple linearregression, should thecollege's leadership be concerned with student performance in large class sizes(greater than 35students) forstatistics? kindly Explain.
7). Using your simple linear regressionmodel, for each one student increase in classsize, how much would one predict theclass' average final grade todecrease?
