Algebra.Com's Answer #241541 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Which of the following statements is correct? \n" ); document.write( "a. For a given level of significance, the critical value of Student's t increases as n increases. \n" ); document.write( "It increases for a left-tail test; It decreases for a right-tail test. \n" ); document.write( "---------------------------------------------- \n" ); document.write( "b. A test statistic of t = 2.131 with d.f. = 15 leads to a clear-cut decision in a two-tailed test where α = .05 \n" ); document.write( "2*tcdf(2.131,1000,15) = 5% \n" ); document.write( "Not a clear-cut decision \n" ); document.write( "----------------------------------------------- \n" ); document.write( "c. It is harder to reject the null hypothesis when conducting a two-tailed test rather than a one-tailed test. \n" ); document.write( "The procedure is similar. \n" ); document.write( "--------------------------------- \n" ); document.write( "If we desire α = 0.10 then a p-value of 0.13 would lead us to reject the null hypothesis. \n" ); document.write( "No; since the p-value is greater that 10% you would fail to reject Ho. \n" ); document.write( "===================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "================== \n" ); document.write( " \n" ); document.write( " |
