Question

nts to find out the relatiannhipbetween the tuition in universities and therraduate rate. Here is the output from data analysis. MuhipleR Adjusted R square the abow output, the modelsirnificantimpartanth explain why or why not. 2. Based on the above output, can we claim that each of the parameter is significant? Explain whw or why not. 3 sita nelable model? How much variation isexplained by this model? 4. What sthe equation from the output? university of Warhirveban's traduate rate in 2015 isd1 what itheestimated tuition in University of Washington in 2015?

Explanation / Answer

1) and 2) Since p-value is < 0.05 the model is significant/important. For each term the p-value is less than zero means we are rejecting null hypothesis i.e.  the coefficient is equal to zero (no effect). Means each term(graduation raise) has an effect on the dependent variable tuition in universaties.

3) Rsquare is 33% so 33% of the variation in dependent variable is explained by the model which is not much relaible.(Rsquare > 80% is a more reliable model.)

4) Equation feom the output

tuition in universities = 164.53*graduation raise+ 14090.22

5) If the graduation rate in 2015 is 61 then 164.53*61 = tuition in universities i.e. 10036.33.
