You have been provided with the original data and two regression models with their corresponding outputs. a) In order to compare the two regression models usign the correct measure for Goodness of fit, What measure should be used? b) Which model has a better goodness of fit? c) Nevertheless, goodness of fit is not everything. You can also use the Partial F- test to verify if the full model is significant compared against the initial reduce model. What is the value of the test statistc F when performing a partial F test? What is the number of degrees (DF) of freedom for the F-statistic? d) Numerator df = e) Denominator df= f) What is the p-value for the F-statistic? R) Based on the outcome of the F-test what is your concussion? Sports & GT Car Acura Integra Type R Acura NSX-T BMW Z3 2.8 Price ($1000s) Curb Weight (lb.)
