Use the sample data for problems 18 & 19 & 20
The Natural Cereal Company claims that the average weight of is cereal boxes is
at least 15oz.
If a random sample of 24 boxes produced a sample mean x = 13.8 and a sample
standard deviation s = 4.8, use the sample mean and standard deviation to test
the claim at the 95% (a = 0.05) significance level.
