If a researcher wishes to determine whether there is evidence that the mean family income in the US is greater than 30,000 then:
\n" ); document.write( "The correct hypothesis setup would be:
\n" ); document.write( "Since \"equality\" must ALWAYS be in the Ho statement,
\n" ); document.write( "Ho: u <= 30,000
\n" ); document.write( "Ha: u > 30,000
\n" ); document.write( "---
\n" ); document.write( "The Ha statement determines the kind of test.
\n" ); document.write( "If Ha is a \"not equal to\" statement, the test is 2-tail
\n" ); document.write( "If Ha is a \"<\" statement, the test is left tail
\n" ); document.write( "If Ha is a \">\" statement, the test is right tail.
\n" ); document.write( "-----
\n" ); document.write( "Your problem is a right tail test.
