Public Health and Nutrition 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.

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.

Let μ represent the mean number of calories consumed per day by an American adult male. State the relevant null and alternative hypotheses in terms of μ.
