Breaking Strength of Cable A special cable has a breaking strength of 800 pounds. The standard deviation of the population is 12 pounds. A researcher selects a sample of 19 cables and finds that the average breaking strength is 795 pounds. Can he reject the claim that the breaking strength is 800 pounds? Use the P-value method with a 0.05 level of significance. Assume that the variable is normally distributed. Use a graphing calculator. what’s the p-value?
