Steel rods are manufactured with a mean length of 24 centimeters (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. Complete parts (a) to (d). (b) Any rods that are shorter than 23.86 cm or longer than 24.14 cm are discarded. What proportion of rods will be discarded?

Steel rods are manufactured with mean length of 24 centimeter (cm): Because of variability in the manufacturing process the lengths of the rods are approximately normally distributed with standard deviation of 0.06 cm . Complete parts (a) to (d) (a) What proportion of rods has ength less than 23.9 cm? 0.0475 (Round t0 four decimal places as needed:) (b) Any rods that are shorter than 23.86 cm or longer than 24.14 cm are discarded: What proportion of rods will be discarded? (Round t0 four decimal places as needed:)

Steel rods are manufactured with a mean length of 25 centimeters (cm). Because of variability in the manufacturing process, the lengths of the rods are approximately normally distributed, with a standard deviation of 0.07 cm. a) What proportion of the rods are shorter than 24.9 cm? b) Any rods that are shorter than 24.85 cm or longer than 25.15 cm are discarded. What proportion of rods will be discarded?
