\n" ); document.write( "x-bar = 10.26
\n" ); document.write( "---
\n" ); document.write( "test stat: t(10.26) = (10.26-9)/[s/sqrt(40)]
\n" ); document.write( "---
\n" ); document.write( "Need the sample standard deviation to get the test stat.
\n" ); document.write( "I should have asked for that.
\n" ); document.write( "But you can insert it and calculate the ts.
