For the following set of data, test the hypothesis that the average is 10. Run a test of that hypothesis and present the conclusion
\n" ); document.write( "x
\n" ); document.write( "8.9
\n" ); document.write( "9.7
\n" ); document.write( "10.3
\n" ); document.write( "8.5
\n" ); document.write( "10.4
\n" ); document.write( "9.3
\n" ); document.write( "9.8
\n" ); document.write( "7.1
\n" ); document.write( "10.6
\n" ); document.write( "11.1
\n" ); document.write( "----------
\n" ); document.write( "Ho: u = 10
\n" ); document.write( "Ha: u is not 10
\n" ); document.write( "------------------
\n" ); document.write( "mu-hat = 9.57 ; s = 1.1767
\n" ); document.write( "-------------------
\n" ); document.write( "Critical value for 2-tail z-test and alpha=5% : +-1.96
\n" ); document.write( "-------------------
\n" ); document.write( "Test statistic:
\n" ); document.write( "z(9.57) = (9.57-10) = -1.1556
\n" ); document.write( "-----------------
\n" ); document.write( "Conclusion: Since test stat is not in the rejection interval
\n" ); document.write( "Fail to reject Ho; test provides statistical evidence that u=10.
\n" ); document.write( "====================
