A race car driver tested his car for the time it takes to go from 0 to 60 mph, and for 20 tests obtained a mean of 4.85 seconds with a standard deviation of 1.47 seconds. These times are known to be normally distributed. What is the value of t used to construct a 95% confidence interval for the mean time it takes the car to go from 0 to 60? Round your answer to 2 decimal places.
