standard deviation of 90 pounds. The company believes that, due to an improvement in the manufacturing process, mean breaking strength, μ, of the cables is now greater than 1775 pounds. To see if this is the case, 39 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1810 pound Assume that the population is normally distributed. Can we support, at the 0.10 level of significance, the claim that population mean breaking strength of the newly-manufactured cables is greater than 1775 pounds? Assume that th population standard deviation has not changed. Perform a one-tailed test. Then complete the parts below.
