The acceleration times (in seconds) from 0 to 60 miles per hour for 26 randomly selected sedans had a sample mean of 7.99 seconds and a sample standard deviation of 1.190. Construct a 98% confidence interval for the population standard deviation. Assume the sample is from a normal population. Enter your answer in interval notation. If your left endpoints 5 and your right endpoint is 7, your answer would be (5, 7). Round your endpoints to three decimal places.
