That is the test is H : = c vrs. H A : 6 = c .

To test this hypothesis we 1 calculated the p-value of the test Lecture 5: Review of Statistical Concepts Simple Linear Regression () Introduction to Econometrics Econ 322, Summer, 2011 June 20, 2011 3 1 One-Sided Hypothesis Tests So far we have looked at two di/erent ways of testing a statistical hypothesis when the alternative is a two-sided alternative. That is the test is H : = c vrs. H A : 6 = c . To test this hypothesis we 1 calculated the p-value of the test 2 set a &amp;xed signi&amp;cance level, calculated the critical value and compared this to the test statistic. Lecture 5: Review of Statistical Concepts Simple Linear Regression () Introduction to Econometrics Econ 322, Summer, 2011 June 20, 2011 3 1 One-Sided Hypothesis Tests (cont) Now consider the 1-sided test H : &amp; c vrs.

H A : &gt; c . or H : c vrs. H A : &lt; c . In order to work out the p-value of a test we need to think about the following: Lecture 5: Review of Statistical Concepts Simple Linear Regression () Introduction to Econometrics Econ 322, Summer, 2011 June 20, 2011 4 / 1 One-Sided Hypothesis Tests (cont) Now consider the 1-sided test H : &amp; c vrs.
