A survey of 6000 adults found that 58% say that they would take a ride in a fully self-driving car. A normal distribution may be used to model the sample proportion.
At 95% confidence, the margin of error for this estimate was 2.4%. Find the 95%
confidence interval of the true proportion who said that they would take a ride in a
self-driving car.
