I am a grad student who has to take this online course to complete my masters but am so lost and desperately need help on my homework. I truly don't understand what to do despite reading and re-reading the chapter and googling for help.
The time required to assemble an electronic component is normally distributed with a mean and a standard deviation of 29 minutes and 14 minutes, respectively.
a. Find the probability that a randomly picked assembly takes between 20 and 34 minutes. (Round "z" value to 2 decimal places and final answer to 4 decimal places.)
b. It is unusual for the assembly time to be above 47 minutes or below 14 minutes. What proportion of assembly times fall in these unusual categories?
