EXAMPLE 3. Table Salt.
A particular brand of table salt is repacked by a retailer
and sold in packs with net weights of 120 g. So long as
the new weights of the packs do not deviate from 120 g by
more than 2 g, the retailer is able to meet the market
specifications and does not incur any loss. To check
whether the repacking process is still under control, he
obtained a random sample of 10 packs. The mean weight
of the sample is 123 g with a standard deviation of 5 g.
Should the retailer have any reason to fear that the
process is out of control? Use a level of significance of .05.
