A soft drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of soft drink. A random sample of 25 bottles is selected, and the contents are measured. The sample yielded a mean content of 11.88 ounces, with a standard deviation of 0.24 ounces. Use a 0.05 level of significance and test to see if the machine is in perfect adjustment (perform all six steps of hypothesis testing, including p-values).© BrainMass Inc. brainmass.com June 4, 2020, 1:04 am ad1c9bdddf
