Vin has decided that what he has called "Vin treatment" is better than STP treatment; STP treatment being better than no treatment (Better = cars go faster!). In order to investigate his question, Vin did the following: (1) flushed the systems of 5 cars, gave them standard treatment and then measured the maximum speed attained of each of the 5 cars (2) flushed the systems of the 5 cars, administered STP treatment to all of the 5 cars and then measured maximum speed attained; (3) flushed the systems of the 5 cars, administered Vin treatment to all oft h e 5 cars and then measured maximum speed attained. The following data were obtained: No STP STP Vin (X2) (X3) St 138 1 4 0 2 0 0 S2 85 80 130 90 88 120 S. 80 85 100 Ss 120 110 155 .1 Determine the independent and dependent variables
