Test the hypothesis that the average weight of the sacks of a powdered raw material is 50 kg if the contents of a random sample of 12 sacks are 50.2, 49.3, 50.1, 49.24, 49.37, 50.24, 49.09, 50.35, 49.08, 49.72, 50.21, and 49.67 kg. Use a 0.05 level of significance and assume the distribution of contents is normal.
