Database Design

Question 1

Please respond to one (1) of the following two (2) items:

• Debate if “failing to reject the null” is the same as “accepting the null.” Support your position with examples of acceptance or rejection of the null. Next, give your opinion on whether or not a failed test “proves” the null hypothesis.
• Take a position on this statement: “In setting up a hypothesis test, the claim should always be written in the alternative hypothesis.” Provide one (1) example to support your position.

Question 2

Why is data modeling an important tool in database design? What problems can occur if we neglect modeling? What modeling tools does our textbook discuss and how are they used effectively?

Question 3

Please respond to the following:

• Elaborate on what the textbook authors mean when they say that most European countries have “divorced America.”
• Explain the main reasons Europe has withdrawn from a close relationship with the U.S.
• What would have to happen, in your opinion, for Europe and the United States to become closer again?
