            beef</a>
          </h5>
<p>
            A machine is set to pack 3 kg of ground beef per pack. Over a long period
            of time it is found that the average packed was 3 kg with a standard
            deviation of 0.1 kg. Assuming the packing is normally distributed, we
            can find the fraction (or %) of packages that weigh more than 3.1 kg.
