Finally, take the average of MPG.city and MPIG.high'v'ltalyr and call it just MPG. We want to do an analysis of MPG vs EngineSize. Question 11 {1 point] The estimates for [30 and [31 for MPG (y) vs EngineSize (x) is: O 37.5302 and -3.2215 respectively O 30.7757 and -3.0020 respectively O 35.1535 and -3.5340 respectively 0 32.1122 and -3.1461 respectively 0 32.6267 and -3.8464 respectively \fQuestion 13 (1 point) What is R2 for MPG (y) vs EngineSize (x). 0.4611 O 0.3929 O 0.722 O0.6184 0.5041Question 14 {1 point] If we test H0: [31 = 0 against Ha: Bi at 0 at 0(=0.025, then the test statistic and conclusions for MPG {y} vs EngineSize (x) are: C] reject HO O not reject H0 Question 15 (1 point] Calculate the correlation coefficient. For MPG (y) vs EngineSize (x), is the data positively or negatively correlated. Choose all the correct answers. C] negatively correlated C] positively correlated
