1.     Please record your SAT score on a sheet of paper without saying your name.
        I will give summary statistics for the class, not individual values in an effort to
        maintain confidentiality and avoid embarrassing anyone.

= ________________                     S = ________________

2.     Test the following hypotheses at the 0.05 significance level:
        H₀:     m < 925
        H₁:     m > 925
 
3.     State your decision from the test in terms of H₀. Interpret this decision--relate
        the result to the average SAT score.
 
4.     What about our sampling procedure should make us cautious about using these
        results?
