Due Day 3 

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: 

a. Discuss the concepts of hypothesis testing, including what you are evaluating.

b. When hypothesis testing should be used.

c. What are the differences between a one- and a two-tailed test? 

d. Describe one example from your personal or professional experiences where you could apply a hypothesis test. Discuss how knowing that information helped you.
