CH7 QUESTION 22
Steel rods are manufactured with a mean length of 25 centimeter (cm). Because of variability in the manufacturing process, the lengths of the rods are approximately normally distributed with a standard deviation of 0.09 cm. (round to four decimal places as needed)
PART A AND B I HAVE DONE I AM JUST PROVIDING IT FOR BETTER INFORMATION
A. What proportion of rods has a length less than 24.8 cm? = 0.0132 (round to four decimal places as needed)
B. Any rods that are shorter than 24.82 cm or longer than 25.18 cm are discarded. What proportion of rods will be discarded? (round to four decimal places as needed)
WHAT I NEED HELP WITH
C. Using the results of part B if 5000 rods are manufactured in a day, how many should the plant manager expect to discard?
Use the answer from part b to find this answer. Round to the nearest integer as needed.
