- A worked example of hypothesis testing is given by a textile manufacturer investigating a new yarn, which claims it has a thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. Using a random sample of 4 specimens, the manufacturer wishes to test the claim that the mean thread elongation is less than 12 kilograms1. Another example is a doctor measuring the blood pressure of 40 patients before and after using a new drug for one month to test if the drug is able to reduce blood pressure in obese patients2.
