Nationally, the proportion of red cars on the road is 0.12. A statistically minded fan of the Philadelphia Phillies (whose team color is red) wonders if Phillies fans are more likely to drive red cars. One day during a home game, he takes a random sample of 210 cars parked at Citizens Bank Park (the Phillies home field), and counts 35 red cars. What are the appropriate hypotheses for performing this significance test? 0:=0.12 :=0.17 where = the true proportion of all cars parked at the Phillies home field that are red. 0:>0.12 ;:=0.12 where = the true proportion of all cars parked at the Phillies home field that are red. 0:=0.12; :>0.12where = the true proportion of all cars parked at the Phillies home field that are red. =0.12; : =0.12 =0.12 where = the true proportion of all cars parked at the Phillies home field that are red. 0:=0.12; :0.12 where = the true proportion of all cars parked at the Phillies home field that are red
