Question: Determine the following values:
n = 479
Σ HP = 116,553
Σ MPG = 9,346
Σ (HP2) = 32,654,855
Σ (MPG2) = 196,038
Σ (HP x MPG) = 2,109,130
Determine the linear correlation coefficient using x = HP and y = MPG. Perform the hypothesis test of rho to determine whether horsepower and gasoline mileage are negatively correlated at the one percent level of significance? [For the critical value, use the maximum df shown on your table.]
