the diameter of a shaft is assembled on a specific component of a space shuttle is made of titanium and must have 97.5 psi tensile strength. from previous quality inspection, it is known that the standard deviation of tensile strength is 10.4 psi. quality engineers took a sample of 25 shafts and measured the tensile strength. the sample average was x=103psi. quality engineers want to be certain that the shafts will have at least 97.5 psi tensile strength. prepare a hypothesis as well as test statistic and P-Value
