Using the infоrmаtiоn belоw cаlculаte the predicted value for Y for the given value of X. Y (Dependent Variable) = Cost of a car in thousands of dollars (i.e. Y = 1 means one-thousand dollars) X (Independent Variable) = Miles per Gallon in city traffic yhat = 28.1 + 0.62*X On average how many thousands of dollars would a car cost if it gets 15 Miles per Gallon in city traffic (round your answer to 4 decimal places)?
