A cereal company sells boxes of cereal that list the weight as
19 oz. A random sample of 60 boxes yielded a mean weight of x =
19.9 oz and a standard deviation s = 0.67 oz. Would this indicate
that the actual weight, µ, of all boxes of this cereal differs from
the weight listed on the box? Perform a hypothesis test at the 5%
significance level.
H0:µ = 19
Ha: µ 6= 19
