Question

A former residential complex was found to be a Superfund site polluted with several hazardous materials. Tamela is an investigative journalist who would like to show whether the proportion of the residents of the complex who eventually died from cancer is greater than the regional average of 14%. She randomly selects 54 residents who lived in the complex and finds that 12 of those residents eventually died from cancer. Are all of the conditions for this hypothesis test met, and if so, what are the null and alternative hypotheses for this hypothesis test?

Respuesta :

Considering the situation described, we have that:

  • The null hypotheses is [tex]H_0: p = 0.14[/tex].
  • The alternative hypotheses is [tex]H_1: p > 0.14[/tex].

What are the hypotheses tested?

At the null hypotheses, it is tested if the proportion at the complex is the same as the rest of the population, that is, of 14%, hence:

[tex]H_0: p = 0.14[/tex].

At the alternative hypotheses, it is tested if it is greater, hence:

[tex]H_1: p > 0.14[/tex].
