Consider two variables regarding Electric Vehicles (EV), Range being the number of miles an EV can travel on a fully charged battery, and Price being the price of the corresponding EV model in 1000 $ (i.e. 40 means $40,000). X:Range (in Mile) Y:Price (in 1000 $) 115 125 105 107 80 60 60 40 (a)Derive the regression coefficients b0 and b1. Show your calcluation. Interpret the meaning of bl. (b)Find R-squared. Interpret the result. (c)Given the estimated standard error (SEb1) for the slope coefficient = 0.145, conduct a hypothesis test with 5% significance level to test if Range is statistically significantly explaining the variability of Price. You have to include all the components of a hypothesis test (hypotheses, decision rule, decision, interpretation). t-table 1234 0.100 3.078 1.886 1.638 1.533 Model 1 2 3 4 0.050 6.314 2.920 2.353 2.132 a 0.025 12.706 4.303 3.182 2.776 0.010 31.821 6.965 4.541 3.747 0.005 9925 5.841 Consider two variables regarding Electric Vehicles (EV), Range being the number of miles an EV can travel on a fully charged battery, and Price being the price of the corresponding EV model in 1000 $ (i.e. 40 means $40,000).
