Hypothesis testing typically begins with a theory, a claim, or an assertion about a particular parameter (mean or proportion) of a population.
The Federal Trade Commission (FTC) is an independent agency of the U.S. federal government charged with preventing unfair or deceptive trade practices. It regulates advertising, marketing, and consumer credit practices, and also prevents antitrust agreements and other unfair practices.
The FTC publishes press releases regularly about health and fitness claims at https://www.ftc.gov/news-events/media-resources/truth-advertising/health-claims

Initial Response: Formulating the Hypothesis
SAMPLE POST FOR GUIDANCE:
1) On May 24, 2016:Mosquito Shield Bands (made by Viatek Consumer Products Group) is a bracelet that contains mint oil and promises to protect people from mosquito bites for up to 120 hours. Viatek claims that Mosquito Shield Bands create a “vapor” barrier that can shield anyone within five feet for 96 to 120 hours.

They are claiming that the mean time for people to be protected from mosquitos is between 96 – 120 hours.
The population parameter is population mean, μ.
2) Null hypothesis, H0: μ = 96 hours
Alternate hypothesis, Ha: μ < 96 hours
3) This would be a left-tailed hypothesis test.
