automation in everyday life. Data was collected from a random sample of Americans age 18 and older. Respondents were asked whether they would want to ride in a driverless vehicle if given the opportunity. Use the survey results to determine if there is convincing evidence that less than 50% of Americans would want to ride in a driverless vehicle if given the opportunity.
