Refer to Exercise 9.30 once again. Suppose that specifications by a buyer of the thread are that the tensile strength of the material must be at least 62 kilograms. The manufacturer is satisfied if at most 5% of manufactured pieces have tensile strength less than 62 kilograms. Is there cause for concern? This time use a one-sided 99%) tolerance limit that is exceeded by 95%) of the tensile strength values.
