Homework Answers
Given, the quality control policy is such that the bolts which are of length more than 2 standard deviations from the mean.The mean length is given to be 13cm and the standard deviation of 0.10cm.
Hence, the upper acceptance limit is : 13 + (2*0.10) = 13.2 cm
So, bolts having length greater than 13.2cm are unacceptable and hence destroyed.
Therefore, Option C
Bolts will be destroyed if length is greater than 13.2 cm.

JUSTIN SHORT Question 6 of 13 Step 1 of S 01:58:05 A bolt manufacturer is very concerned about the consistency with which his machines produce bolts. The bolts should be 0.24 centimeters in diameter. The variance of the bolts should be 0.015. A random sample of 12 bolts has an average diameter of 0.23 cm with a standard deviation of 0.0642. Can the manufacturer conclude that the bolts vary by less than the required variance at a = 0.05 level?...
