A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 4 standard deviations from the mean. The quality-control engineer knows that the bolts coming off the assembly line have mean length of 12 cm with a standard deviation of 0.05 cm. For what lengths will a bolt be destroyed? Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to one decimal place as needed.) O A. A bolt will be destroyed if the length is between cm and cm. B. A bolt will be destroyed if the length is less than cm. O C. A bolt will be destroyed if the length is less than cm or greater than cm. O D. A bolt will be destroyed if the length is greater than cm.
