When you drive a car and suddenly see an obstacle in your way, you cannot stop immediately; your car will pass some distance after you start to apply the brakes. This distance depends on many factors, including the car velocity, the quality of the road surface, and the quality of the tires. The sample mean for the braking distance of a sedan car moving at 40 mph on dry asphalt is 68 . 73 ft . Assume that a bootstrap distribution was built, and the standard error is 3.35 . Find an estimated \( 95 \% \) confidence interval for mean braking distance using the data. \( (65.29,68.73) \) \( (62.03,75.43) \) \( (65.29,72.15) \) \( (65.39,72.08) \)
