Please answer number 7. Please make sure to show work!! Thx.
2. 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. 7. 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. (b) find an interval containing the corresponding P-value for a right-tailed test.
