Using your dataset, run a regression of Y=GPA and X=# Friends. (Include your print out with your answers–I do not need your actual data, just the regression results) a) State what this regression is attempting to analyze. "By running this regression, we are attempting to show." b) Run the regression (attach pdf/scan of results) c) Write out the regression equation and interpret the results. d) Find your hypothesized GPA when the # friends equals 17. e) Test that the slope is significantly different from zero. Include Ho, Ha, decision rule, t statistic from table, tc, decision, and conclusion. f) Test that the coefficient of determination is significantly different from zero. Include Ho, Ha, decision rule, F statistic from table, Fc, decision, and conclusion.
