\n" ); document.write( "Use a t table such as this one
\n" ); document.write( "http://www.ttable.org/
\n" ); document.write( "which can be found in the back of statistics textbooks. At the bottom of the table, it shows 99% confidence interval. Highlight the entire column. Then highlight the entire row with df = 19, where df stands for \"degrees of freedom\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This diagram shows what I mean
\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The row and column intersect at the value 2.861
\n" ); document.write( "This means, P( -2.861 < T < 2.861 ) = 0.99\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: 2.861
\n" ); document.write( "This value is approximate
\n" ); document.write( "
