Question: The Prescott Swamp Water Bottling Company also bottles soft drinks, their Swampy Diet Cola Drink with a tinge of Alligator , is a local favorite among the teenage set. (They will drink anything.) The company uses an automatic filling machine to do the bottling. When the machine is working properly (which seems to be rarely), the mean fill is 12 ounces per can with a standard deviation of 0.20 ounces. Each day Rusty Springs selects a random sample of 36 cans and measures the volume in each can. He then tests to determine whether the filling process is working properly. The test is conducted at the 0.05 significance level. So what is the critical value in ounces ? (NOTE: Here you are not looking to accept or reject the null, just give me the range. Also, I’d start by writing out the hypotheses – it’s easier.)
