A particular manufacturing design requires a shaft with a diameter of 21 000 mm, but shafts with diameters between 20 991 mm and 21.009 mm are acceptable. The manufacturing process yields shafts with diameters normally distributed, with a mean of 21 002 mm and a standard deviation of 0 006 mm Complete parts through (d) below. a. For this process, what is the proportion of shafts with a diameter between 20.991 mm and 21.000 mm? The proportion of shafts with diameter between 20.991 mm and 21.000 mm is (Round to four decimal places as needed)
