Before agreeing to purchase a large order of polyethylene sheaths for a particular type of high-pressure oil-filled submarine power cable, a company wants to see conclusive evidence that the true standard deviation of sheath thickness is less than 0.04 mm. What hypotheses should be tested, and why? The appropriate hypotheses are H0: σ ?<>≠= 0.04 mm versus Ha: σ ?<>≠= 0.04 mm. With this formulation, the burden of proof is on the data to show that the requirement ---Select---hashas not...

Imagine that you are testing an experimental drug that is supposed to reduce blood pressure but is suspected of inducing cancer. You administer the drug to a sample of rodents. Since you know that the tumor rate in this strain is 10% among untreated animals, your null hypothesis (the one which includes an equals sign) is that the tumor rate in treated animals is less than or equal to 10%, that is, the drug is safe, it does not cause...

Many Americans have high blood pressure which can lead to a number of serious conditions including heart attack and stroke. There are a number of drugs available to treat high blood pressure, but researchers are always seeking new ones with fewer side effects. In this experiment, researchers randomly selected 20 women from a pool with high-normal blood pressure to high blood pressure and measured their initial systolic blood pressure (in mm of Hg). They treated the subjects with an experimental...

Caffeine is a stimulant widely used by the general human population and may have an effect on oxygenation within the bloodstream. You are tasked with evaluating coffee consumption (due to its high caffeine content) to see if there is an effect of caffeine on the oxygen partial pressure (PO2) of blood in normal subjects. In the first group, the subjects are placed on a no coffee diet, while the second group of subjects have at least 2 cups of coffee...
