Develop an estimated multiple linear regression model that could be used to predict the alumni giving rate using the graduation rate, % of classes under 20, and studen a. true b. falseaculty ratio as 2 | page independent variables. discuss your findings. how much of the variation in the sample of values of dependent variable does the regression model explain? using the f test, is the overall regression statistically significant at the 0.05 level of significance? if so, using the t test, then test whether each of the regression parameters of the model is equal to zero at a 0.05 level of significance (for each statistical test, write down the null and alternative hypotheses).
