EN>Steel rods are manufactured with a mean length of 20 centimeter (cm). Because of variability in the manufacturing process, the lengths of the rods are approximately normally distributed with a standard deviation of0.07 cm. Complete parts (a) to (d)(a) What proportion of rods has a length less than 19.9 cm?(Round to four decimal places as needed.)(b) Any rods that are shorter than 19.83 cm or longer than 20.17 cm are discarded. What proportion of rods will be discarded?(Round to four decimal places as needed.)(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.)(d) If an order comes in for 10,000 steel rods, how many rods should the plant manager expect to manufacture if the order states that all rods must be between 19.9 cm and 20.1 cm?(Round up to the nearest integer.)Enter your answer in each of the answer boxes.8:36 PMType here to searchOEH10/20/201919ASUSpausebreakprt scSysraf7f819f1012insertdeletef1f2f3f4f5f6escZtr&backspaceA2#3$4578070יוPtabWERTY
