3. Statistical Literacy When using the Student's t distribution to test μ, what
value do you use for the degrees of freedom?
4.
Statistical Literacy To test μ for an x distribution that is mound-shaped us-
ing sample size n ≥ 30, how do you decide whether to use the normal or the
Student's t distribution?
Critical Thinking Consider a test for u. If the P-value is such that you can
reject H, at the 5% level of significance, can you always reject H, at the 1%
level of significance? Explain.
5. Critical Thinking Consider a test for μ. If the P-value is such that you can
reject H for a = 0.01, can you always reject H, for a = 0.05? Explain.

6. Critical Thinking If sample data is such that for a one-tailed test of μ you
can reject H at the 1% level of significance, can you always reject H for a
two-tailed test at the same level of significance? Explain.
Basic Computation: P-value Corresponding to t Value For a Student's t
distribution with d.f. = 10 and t = 2.930,
(a) find an interval containing the corresponding P-value for a two-tailed test.
