13. [I9.61 Points] DEVORESTAT9 7.2.017. ASK YOUR TEACHER A sample of ultimate tensile strength observations (ksi) was taken. Use the accompanying descriptive statistics output from Minitab to calculate a 99% lower condence bound for true average ultimate tensile strength, and interpret the result. (Round your answer to two decimal places.)
