In a report concerning the rise of automation in the United States, of the participants indicated that they would not ride in a driverless car, and favor a requirement of having a human in the driver's seat in case of an emergency. Suppose that the number of participants was n conclude that more than a simple majority of Americans would not ride in a driverless car? 420. Is there sufficient evidence to (a) (b) IA USE SALT use a formal test of hypothesis with a = 0.05 to determine whether more than 500,' of Americans would not ride in a driverless car. State the null and alternative hypothesis. O Ho: p = 0.5 versus H OH : p = 0.5 versus H O Ho: 0.5 versus H O Ho: p < 0.5 versus H O Ho: p = 0.5 versus H : p < 0.5 : 0.5 0.5 Find the test statistic. (Round your answer to two decimal places.) Find the rejection region. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.) State your conclusion. is rejected. There is insufficient evidence to indicate that more than of Americans would not ride in a driverless car. is not rejected. There is sufficient evidence to indicate that more than 50',' of Americans would not ride in a driverless car. is not rejected. There is insufficient evidence to indicate that more than of Americans would not ride in a driverless car. is rejected. There is sufficient evidence to indicate that more than of Americans would not ride in a driverless car. use the p-value approach. (use a = 0.05.) Find the p-value. (Round your answer to four decimal places.) p-val ue = State your conclusion. 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 greater than alpha so H is not rejected. There is insuffcient evidence to indicate that more than of Americans would not ride in a driverless car. O The p-value is greater than alpha so H is not rejected. There is sufficient evidence to indicate that more than 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 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 different conclusions. O The two approaches lead to the same conclusion.
