Bags filled by a machine have masses that are normally distributed with a mean which is set by the operator and a standard deviation of 0.1 kg. A quality requirement being followed is that only 1% of the bags should weigh less than 10 kg. What should the operator set the mean to be so that this requirement is met? Make use of the normal tables
