4 Concrete blocks are manufactured to be 5 kg in weight, but are accepted if they are between 4.96 and 5.04 kg. In the long run, 1% of the blocks are rejected as overweight and 1% are rejected as underweight. Calculate the standard deviation of the weight of the blocks if the weights are normally distributed.
