Question

A particular manufacturing design requires a shaft with a diameter between 21.89 mm and 22.010 mm. The manufacturing process yields shafts with diameters normally​ distributed, with a mean of 22.002 mm and a standard deviation of 0.004 mm. Complete parts​ (a) through​ (c).

a. For this process what is the proportion of shafts with a diameter between 21.8921.89 mm and 22.00 mm?

The proportion of shafts with diameter between 21.89 mm and 22.00 mm is

B. For this process the probability that a shaft is acceptable is? (Round to four decimal places)

C. For this process the diameter that will exceed by only 1% of the shafts is (blank) mm? (Round to four decimal places)
