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

That is the test is H : = c vrs. H A : 6 = c . To test this hypothesis we 1 calculated the pvalue of the test Lecture 5: Review of Statistical Concepts Simple Linear Regression () Introduction to Econometrics Econ 322, Summer, 2011 June 20, 2011 3 1 OneSided Hypothesis Tests So far we have looked at two di/erent ways of testing a statistical hypothesis when the alternative is a twosided alternative. That is the test is H : = c vrs. H A : 6 = c . To test this hypothesis we 1 calculated the pvalue of the test 2 set a &xed signi&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 OneSided Hypothesis Tests (cont) Now consider the 1sided test H : & c vrs. H A : > c . or H : c vrs. H A : < c . Lecture 5: Review of Statistical Concepts Simple Linear Regression () Introduction to Econometrics Econ 322, Summer, 2011 June 20, 2011 4 / 1 OneSided Hypothesis Tests (cont) Now consider the 1sided test H : & c vrs. H A : > c . or H : c vrs. H A : < c . In order to work out the pvalue 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 OneSided Hypothesis Tests (cont) Now consider the 1sided test H : & c vrs.
