16 20
17 15
15 19
a. What statistical test should be used to analyze the data?

b. Is this a one- or two tailed test?

c. Identify H0 and Ha for this study.

d. Conduct the appropriate analysis. Should H0 be rejected?

  • statistics -

    Try an independent groups t-test. This will be a two-tailed test because the problem is just asking if there is a difference, which could be in either direction.

    Ho: µ1 = µ2 -->population means are equal
    Ha: µ1 does not equal µ2 -->population means are not equal

    I hope this will help get you started.
