A local grocery store sells individually packaged slices of cake, all labeled with the same weight of 4 oz.
Suppose we take a random sample of 49 cake slices and record their weights. The mean weight of our sample of 49 slices is 4.2 oz.
Assume that the population standard deviation is 0.2 oz.
True or false? It is very likely that the actual cake slice weight mean is higher than 4 oz..
