Automobiles Purchased An automobile owner found that 20 years ago, 76% of Americans said that they would prefer to purchase an American automobile. He believes that the number is much greater than 76% today. He selected a random sample of 58 Americans and found that 50 said that they would prefer an American automobile. Can it be concluded that the percentage today is greater than 76%? At a=0.10, is he correct? Use the P-value method with tables. Do not round intermediate steps. Part 1 of 5 State the hypotheses and identify the claim with the correct hypothesis. Ho: p.76 not claim H₁: p.76 claim This hypothesis test is a one-tailed ▼ test. Alternate Answer: Ho: p=0.76 not claim H₁ :p>0.76 claim This hypothesis test is a one-tailed test. Part: 1/5 Part 2 of 5 Compute the test value. Always round z score values to two decimal places. Z= X 3
