II. Students were asked to indicate their height in feet. Assume
that the following random sample comes from a population that
is normally distributed:
6.00 6.17 5.50 5.58 5.67 6.00 5.25
5.75 5.17 6
.08 5.25 5.75 5.75
5.83 6.33 5.58 5.83 5.00

Does the above sample come from a population with u = 5.50
(use a = .05, two-tailed)?
A. What are the null hypothesis and the alternative
hypothesis?
B. What are the critical value(s) (make sure to indicate
what degrees of freedom were used to determine this)?
C. Use SPSS to calculate your test statistic.
D. Explain why you would or would not reject the null
hypothesis.
E. Use SPSS to calculate a 95% CI for the mean height of
students.
III. Statistics students were asked to indicate their political
orientation (republican or democrat) and then rated their degree
of conservativeness (1 = not at all, 7 = extremely). Assume that
