Do physical exercises help individuals to age gracefully. The dependent variable is the frequency of doctors visits the assumed effect. Writing a hypothesis begins with a research question that you want to answer.

Arbuthnot used birth data to determine with high statistical probability that there are more male births than female births. A composite hypothesis does not specify the population distribution completely. We therefore expect that there are infinitely many primes This has not been proved though.

H 0 innocent is rejected if H 1 guilty is supported by evidence beyond reasonable doubt Failure to reject H 0 prove guilty does not imply innocence only that the evidence is insu cient to reject it.

H0 is a null hypothesis while H1 is an alternative hypothesis. The question should be focused specific and researchable within the constraints of your project. Each sample produces one of four possible results.
