A manufacturing company produces valves in various sizes and shapes. One particular valve plate is supposed to have a tensile strength of 5 pounds per millimeter (lbs/mm). The company tests a random sample of 42 such valve plates and finds a sample mean of 5.0611 lbs/mm and a standard deviation of 0.2803 lbs/mm. a) What is the appropriate null and alternate hypothesis to determine if the average tensile strength of the valve plate is different than 5 lbs/mm?b) Using \alpha= 0.10, what are the critical values for the hypothesis test?c) What is the test statistic for the hypothesis test?d) Draw a conclusion for the hypothesis test. Make sure you state your conclusion in the context of the problem. e) Calculate the p-value for the hypothesis test.
