A polymer-coated nylon weave is aged by exposing it to 158 degrees F for 168 hours. The tensile strength of the specimens of this material is measured before and after the aging process.

Is there evidence to support the claim that the nylon weave tensile strength is the same before and after the aging process? Be sure to state Hypotheses clearly, give all summary data, state Test used, show Test Statistics formula and value, and show how to find the P-value. Write an appropriate conclusion using α = 0.01. 5b. Show all steps (including how to find cutoff value) and construct a two-sided 98% Confidence Interval for the true mean difference.
