Claim: The population mean is 425. Sample data: n = 18, x bar = 438, s = 21.3. The data was taken from a simple random sample collected from a normally distributed population with a population standard deviation of 18.4.

\n" ); document.write( "Ho: u = 425
\n" ); document.write( "H1: u is not equal to 425
