A bolt company produces half-inch steel bolts that have a mean tensile strength of more than 3,500 lbs. the specified quality standard. Make sure the product does not fall below the standard. A sample of 20 bolts are randomly selected and tested for tensile strength. Design a test of hypothesis to determine if there is overwhelming evidence that the bolts meet the quality standards. The avg tensile strength of the sample is 3,550 Ibs with a std of 12. Test at alpha = .01 Ho: H CV = Ha: TS = Decision
