x 6.2.13-T Question Help A particular manufacturing design requires a shaft with a diameter of 17.000 mm, but shafts with diameters between 16.990 mm and 17.010 mm are acceptable. The manufacturing process yields shafts with diameters normally distributed, with a mean of 17.005 mm and a standard deviation of 0.006 mm. Complete parts (a) through (d) below. a. For this process, what is the proportion of shafts with a diameter between 16.990 mm and 17.000 mm? The proportion of shafts with diameter between 16.990 mm and 17.000 mm is 0.1971 (Round to four decimal places as needed.) b. For this process, what is the probability that a shaft is acceptable? The probability that a shaft is acceptable is (Round to four decimal places as needed.)
