A researcher wants to estimate the mean tread life of a particular type of automobile tire. A randomly selected 14 tires of the particular type are tested. The mean tread life of the 14 tires is 65,201 miles with a standard deviation of 1,386 miles. Construct a 99% confidence interval for the mean tread life of that type of tire. In the next question, you will enter the upper limit of the interval. For now, enter the lower limit of the interval, rounded to nearest whole number.
