Your initial post, will consist of three parts:

• Describe real-world situation when you thought about the value of a measurement and stated a conclusion about the likelihood that it is true
• Clearly state your null and alternative hypotheses
• Identify your example as a one-tailed or two-tailed test

Instructor's Example:

1) I am sure that the average time it takes me to get ready each morning is 30 minutes.

2)

3) This is a one tailed test since I am testing for the possibility of the relationship in only one direction.
