Show transcribed image text Question 24 1 pts 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 n1 = 40 X1 = 5.9 S1 = 1.6 Ages for student cars n2 -36 X2=7.1 $2 = 1.8 Find the rejection region at α = 0.05. Rejection region: z>1.645 Rejection region: z > 1.96 Rejection region: z -1.645 Rejection region: z -1.96 Rejection region: z -1.645
