I. In a shipment of 300 connecting rods, the mean tensile strength is found to be 45 kpsi and has a standard deviation of 5 kpsi. (a) Assuming a normal distribution, how many rods can be expected to have a strength less than 39.4 kpsi? (b) How many are expected to have a strength between 39.4 and 60 kpsi?
