10.    The stiffness of a certain type of steel beam used in building construction has mean 30 kN/mm and stan- dard deviation 2 kN/mm.
Â
a.   Is it possible to compute the probability that the stiffness of a randomly chosen beam is greater than 32 kN/mm? If so, compute the probability. If not, explain why not.
Â
b.   In a sample of 100 beams, is it possible to com- pute the probability that the sample mean stiffness of the beams is greater than 30.2 kN/mm? If so, compute the probability. If not, explain why not.
