discussion question

1. A company's customer support division wants to test to see if wait time for a consumer to talk to a representative is under 10 minutes.  The manager proposes to test one case where a consumer was placed on hold.  Is this a good testing strategy?  If not what would be a better testing strategy?  Could you form a Null Hypothesis or an Alternative Hypothesis?  If yes, what would they be?

2. Use a specific example to explain what a point estimation is and what a confidence interval is.
