A doctor claims that there is 800 milligrams of helpful
medicine per fluid ounce as an active ingredient in the
sleep medication. A test of 93 one-ounce samples of
the sleep medication finds that the mean amount of
helpful medicine for the sample is 722 milligrams with
a standard deviation of 45 milligrams. What would be
the steps to test the claim that the sleep medication
does not contain the required amount of helpful
medicine if you used a 0.05 significance level? In a
few sentences, how could this apply to your work in
another area? For instance, presenting to hospital
staff or administration?
