Answer each of the following questions with complete sentences.  Include a brief explanation in complete sentences.  A. You are reading an article in your field that reports several statistical analyses.  The article says that the P-value for a significance test is 0.045.  Is this result significant at the 5% significance level?  B.  Is the result with P-value 0.045 significant at the 1% significance level?  C.  For another significance test, the article says only that the result was significant at the 1% level.  Are such results always, sometimes, or never significant at the 5% level?    D.  The reaction times of a subject to a stimulus are strongly skewed to the right because of a few slow reaction times.  You wish to test            Ho:  μ1 = μ2 where μ1 is the mean reaction time for Stimulus 1, and μ2 for Stimulus 2.  You have two independent samples, 8 observations for Stimulus 1 and 10 for Stimulus 2.  Which, if any, of the tests you have studied can be used to test this? E.     You read an article that contains a 95% confidence interval.  Would the margin of error in a 99% confidence interval computed from the same data be less, the same, or greater?

Answer each of the following questions with complete sentences.  Include a brief explanation in complete sentences. 

A. You are reading an article in your field that reports several statistical analyses.  The article says that the P-value for a significance test is 0.045.  Is this result significant at the 5% significance level?

 B.  Is the result with P-value 0.045 significant at the 1% significance level?

 C.  For another significance test, the article says only that the result was significant at the 1% level.  Are such results always, sometimes, or never significant at the 5% level?  

 D.  The reaction times of a subject to a stimulus are strongly skewed to the right because of a few slow reaction times.  You wish to test            Ho:  μ1 = μ2

where μis the mean reaction time for Stimulus 1, and μ2 for Stimulus 2.  You have two independent samples, 8 observations for Stimulus 1 and 10 for Stimulus 2.  Which, if any, of the tests you have studied can be used to test this?

E.     You read an article that contains a 95% confidence interval.  Would the margin of error in a 99% confidence interval computed from the same data be less, the same, or greater?
