n = 33
\n" ); document.write( "sample mean = 12.15
\n" ); document.write( "sample standard deviation = .11
\n" ); document.write( "claim is population mean is 12
\n" ); document.write( "standard error = sample standard deviation / square root of sample size = .11/sqrt(33) = .01915.
\n" ); document.write( "t-score = (x - m) / s = (sample mean minus assumed mean) / standard error = (12.15 - 12) / .01915 = 7.83.
\n" ); document.write( "that would be the test statistic.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
