```										Hello student,Please find the answer to your question belowGivenThe safety limit of a crane is known to be 32 tons. The mean weight and the standard deviation of a large number of iron rods are 0.3 ton and 0.2 ton respectively. 100 rods are lifted at a time.mean=0.3standard deviation=0.2/sqrt(100)=0.02So standardized value of sample mean 0.32 is =0.32-0.3/0.02=1Probability that x>0.32 is are of standard normal curve to the right of ordinate at z=1 which is 0.1587
