The lifetime of a certain transistor in a certain application has mean 900 hours and standard deviation 30 hours. Find the mean and standard deviation of the length of time that four bulbs will last.
What will be an ideal response?
Let 
be the lifetimes of the four transistors. Let 
be the total lifetime.
