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 13 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.) OA. A bolt will be destroyed if the length is less than OB. A bolt will be destroyed if the length is greater than cm. OC. A bolt will be destroyed if the length is between OD. A bolt will be destroyed if the length is less than cm.

Determine whether the statement is true or false. If it is false, rewrite it as a true statement. As the size of a sample increases, the standard deviation of the distribution of sample means increases. Choose the correct choice below. C OA. This statement is false. A true statement is, "As the size of a sample increases, the standard deviation of the distribution of sample means decreases." OB. This statement is true. OC. This statement is false. A true statement is, "As the size of a sample decreases, the standard deviation of the distribution of sample means decreases." OD. This statement is false. A true statement is, "As the size of a sample increases, the standard deviation of the distribution of sample means does not change." Time Remaining: 01:26:37
