Hypothesis testing allows us to use an analytical process to determine if a hypothesis is retained OR rejected. This process compares a null hypothesis (HO), which states things as we believe they are, to an alternative hypothesis (HA), which proposes a change to what we believe exists.    Respond to the following in a minimum of 175 words:  Discuss the concepts of hypothesis testing, including what you are evaluating, when it should be used, and the differences between a one- and a two-tailed test.  Describe an example from your own personal or professional experiences where you could apply a hypothesis test, and discuss how knowing that information helped you.
