Because of variability in the manufacturing process, the lengths of the rods are approximately normally distributed with a standard deviation of 0.09 cm. Click the icon to view a table of areas under the normal curve. (@) What proportion of rods has a length less than 23.9 cm? X (Round to four decimal places as needed.) Tables of Areas under the Normal Curve (b) Any rods that are shorter than 23.81 cm or longer than 24.19 cm are discarded. What proportion of rods will be discarded? (Round to four decimal places as needed.)
