(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 23.9 cm and 24.1 cm? Mean: 24 Standard Deviation: .06
Rashmi S.
Steel rods are manufactured with a mean length of 26 centimeters. Due to variability in the manufacturing process, the lengths of the rods are approximately normally distributed with a standard deviation of 0.06 cm. a. What portion of rods has a length less than 25.9 cm? b. Any rods that are shorter than 25.86 cm or longer than 26.14 cm are discarded. What proportion of rods will be discarded? c. Using the results of part b, if 5000 rods are manufactured in a day, how many should the plant manager expect to discard? 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 25.9 cm and 26.1 cm?

Steel rods are manufactured with a mean length of 23 centimeter (cm). Because of variability in the manufacturing process, the lengths of the rods are approximately normally distributed with a standard deviation of 0.06 cm. a. (a) What proportion of rods has a length less than 22.9 cm b.Any rods that are shorter than 22.87 cm or longer than 23.13 cm are discarded. What proportion of rods will be discarded? c.Using the results of part (b), if 5000 rods are manufactured in a day, how many should the plant manager expect to discard? (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 22.9 cm and 23.1 cm?
