ufacturer 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 co bly line have mean length of 15 cm with a standard deviation of 0.10 cm. For what lengths will a bolt be destroyed? the correct choice below and fill in the answer box(es) to complete your choice. d to one decimal place as needed.) A bolt will be destroyed if the length is less than A bolt will be destroyed if the length is between F. A bolt will be destroyed if the length is greater than 5. A bolt will be destroyed if the length is less than cm. cm and cm. cm. cm or greater than cm. CITE
