Pedro is trying to solve the following problem. "In a sample of 200 Californians, 139 of them own a car. In a sample of 300 Texans, 62% own a car. Is there a difference in the proportions?" Here is his work: Step 1 : Ho : P1 = P2, p = 280/400 - 0.7, p2 0.62, > p = 0.67 Ha : Pi # P2 0.70 - 0.62 Step 2: Z* = 1.7 V(0.7) (0.3) (1/200 + 1/300) Step 3: Rejection Region: | Zo.025 = 12.33 Step4: Since 2.3 is not in the Rejection Region then we Fail to reject Ho Find ALL the mistakes in his work and provide the correct solution to the steps
