****************** A sample of ultimate tensile strength observations (ksi) was taken. Use the accompanying descriptive statistics output from Minitab to calculate a 99% lower confidence bound for true average ultimate tensile strength, and interpret the result. (Round your answer to two decimal places.) N 153 Mean 131.36 Median TrMean 131.37 131.38 St Dev 4.59 SE Mean 0.37 Minimum 123.10 Maximum 148.70 We are 99% confident that the true average ultimate tensile strength is greater than 131.28 You may need to use the appropriate table in the Appendix of Tables to answer this question. Q1 132.75 Xksi. Q3 139.45
