Identify a research question from your professional life, research interests, or everyday experience that could be addressed by this analysis.

  Determining the null and alternate hypotheses

Assume that in a hypothesis test with null hypothesis H 0  : μ = 14.0 at a = 0.05, that a value of 13.0 for the sample mean results in the null hypothesis not being rejected. That corresponds to a confidence interval result of:
