Answer 1

Answer :-

Given that,

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.

You may need to use the appropriate table in the Appendix of Tables to answer this question.

One more plausibility that strikes a chord is to take a gander at the first differential condition y[t] +2.51 y[t] = 0.5 Sin[V2.51]
