The time required to assemble an electronic component is normally distributed with a mean and standard deviation of 16 minutes and 8 minutes, respectively.

a. Find the probability that a randomly picked assembly takes between 10 and 20 minutes. (Round "z" value to 2 decimal places and final answer to 4 decimal places.) Probability=

b. It is unusual for the assembly time to be above 24 minutes or below 6 minutes. What proportion of assembly times fall in these unusual categories? (Round "z" value to 2 decimal places and final answer to 4 decimal places.) Proportion of assembly times=
