The distance of commutes to work for 14 randomly selected adults were computed. The distances (in miles) are given below: 3.75 5 9 12.5 14 6.25 7 20 17 8.5 11 4 16.5 13 Assuming the distances of commutes are approximately normally distributed, do the following a.) Construct a 90% confidence interval for the mean distance of commutes. (Round all answers to 3 decimal places when applicable.) Sample Mean: x Sample Standard Deviation: S Degrees of Freedom: t-score: ta - to.05 90% CI: [
