Of a random sample of 1,200 people in Country A, 720 had a positive attitude toward car salespeople. Of an independent random sample of 1,000 people in Country B, 580 had a positive attitude toward car salespeople. Test, at the 10% level, the null hypothesis that the population proportions are equal against the alternative that a higher proportion of citizens of Country A have a positive attitude toward car salespeople. Click the link to view a standard normal distribution table. Let Px be the proportion of people in Country A who said they had a positive attitude toward car salespeople and Py be the proportion of people in Country B who said they had a positive attitude toward car salespeople. Determine the null and alternative hypotheses. Choose the correct answer below. O A. Ho: Px-Py = 0 H₁: Px-Py #0 OD. Ho: Px-Py = 0 H₁: Px-Py 20 O B. Ho: Px-Py = 0 H₁: Px-Py ≤0 E. Ho: Px-Py = 0 H₁: Px-Py >0 O C. Ho: Px-Py #0 H₁: Px-Py = 0 = 0 OF. Ho: Px-Py= H₁: Px-Py <0
