In a report concerning the rise of automation in the United States, 56% of the participants indicated that they would not ride in a driverless car, and 81% favor a requirement of having a human in the driver's seat in case of an emergency. Suppose that the numb of participants was n = 450. Is there sufficient evidence to conclude that more than a simple majority of Americans would not ride in a driverless car?

State your conclusion.
O The p-value is greater than alpha so Ho is not rejected. There is insufficient evidence to indicate that more than 50% of Americans would not ride in a driverless car.

USE SALT
(a) Use a formal test of hypothesis with a = 0.05 to determine whether more than 50% of Americans would not ride in a driverless car.
State the null and alternative hypothesis.
O Ho: P < 0.5 versus H₂: p > 0.5
O Ho: P = 0.5 versus H₂: p < 0.5
O Ho: P = 0.5 versus H₂: p = 0.5
O Ho: P = 0.5 versus H₂: p = 0.5
O Ho: P = 0.5 versus H₂: p > 0.5
Find the test statistic. (Round your answer to two decimal places.)
z =
Find the rejection region. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.)
