Transcribed Image Text:Suppose a company sells bacon in packages that
they claim average a weight of 14 ounces.
Timothy believes that the actual average weight
of the packages is different than what the
company claims, and would like to test this using
a significance level of 0.02. He takes a random
sample of 51 packages and gets a sample mean
of 14.55 ounces and a sample standard deviation
of 1.16 ounces.
