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?

(b) Use the p-value approach. (Use α = 0.05.)
Find the p-value. (Round your answer to four decimal places.)
p-value =
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.
O The p-value is less than alpha so Ho is rejected. There is insufficient evidence to indicate that more than 50% of Americans would not ride in a driverless car.
O The p-value is less than alpha so Ho is rejected. There is sufficient evidence to indicate that more than 50% of Americans would not ride in a driverless car.
O The p-value is greater than alpha so Ho is not rejected. There is sufficient evidence to indicate that more than 50% of Americans would not ride in a driverless car.
Do the two approaches lead to the same conclusion?
O The two approaches lead to the same conclusion.
O The two approaches lead to the different conclusions.

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 numbe
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?
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.)
Z >
Z <
State your conclusion.
O Ho is rejected. There is sufficient evidence to indicate that more than 50% of Americans would not ride in a driverless car.
O Ho is not rejected. There is insufficient evidence to indicate that more than 50% of Americans would not ride in a driverless car.
