The Savannah Sugar Refinery in Louisiana will invest in new energy-saving devices if there is evidence to suggest that the mean amount of energy (in kilowatts) used per day will decrease from 1925. Suppose m is the population mean amount of energy used per day, and an experiment is designed to test the new equipment. State the null and alternative hypotheses in terms of

Suppose U.S. monetary policy will be set by the Federal Reserve Board by examining the median consumer price,
for a large fixed set of common commodities. The Board will raise the interest rate if there is evidence that the median price is less than $125.50.

The typical American adult male consumes approximately 2666 calories per day. New research suggests that those people who stay up late lose more sleep and consume more calories.7 A random sample of 125 American adult males who routinely stay up late was obtained, and the number of calories per day consumed by each was carefully recorded.
