A car dealer claims that on average, cars owned by professors are newer than cars owned by students. Random samples of 40 faculty cars and 36 students cars are taken and their ages are measured. The data was shown in the following table: Ages for faculty cars Ages for student cars n1 = 40 X1 = 5.9 $1 = 1.6 n2 = 36 X2 = 7.1 52 = 1.8 Choose the correct hypotheses to test the claim.
