An automobile engineer would like to test his newly invented anti-lock braking system. specifically, he would like to calculate the average number of feet it takes the brakes to stop a car going 50 miles per hour. the engineer took a sample of 6 cars and from this sample calculated a mean stopping distance of 15 feet with a standard deviation of 2.28 feet. assuming stopping distances are normally distributed, what is the 80% confidence interval for the population mean?
