Question 10 (1 point] Calculate the correlation coefficient. For MPG.highway (y) vs EngineSize (x), is the data positively or negatively correlated. Choose all the correct answers. negatively correlated 0.63 positively correlated -O.71 -0.63 We will next examine mileS per gallon on the highway {MPG.highway) V5 engine size (EngineSize). Question 6 (1 point} The estimates for BC} and B1 for MPG.highway (y) v5 EngineSize (x) is: 0 32.6267 and -3.3464 respectively 0 37.6302 and -3.2215 respectively 0 30.7767 and -3.0020 respectively 0 35.1535 and -3.5340 respectively 0 32.1122 and -3.1461 respectively Question 7 (1 point) What is s for MPG.highway (y) vs EngineSize (x). 3.555 4.177 O 2.813 3.979 3.985Question 8 (1 point) What is R2 for MPG.highway (y) vs EngineSize (x). 0.6184 0.3929 O 0.7222 0.5041 0.4611Question 9 (1 point) If we test H0: [31 = 0 against Ha: Bl at 0 at 0(=0.025, then the test statistic and conclusions for MPG.highway (y) vs EngineSize {x} are: C] reject HO O not reject H0 C] -9.618
