Algebra.Com's Answer #164056 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! A newspaper reports several statistical analyses. It reports that the \n" ); document.write( "P-value for a significance test is 0.045. \n" ); document.write( "a) Is the result significant at the 5% significance level? \n" ); document.write( "No the test did not reach the significance level of 5% \n" ); document.write( "--------------------------------------------------\r \n" ); document.write( "\n" ); document.write( "b). Is the result with P-value 0.045 significant at the 1% level? \n" ); document.write( "Yes the test reached the significance level of 1%\r \n" ); document.write( "\n" ); document.write( "-------------------------------------------------- \n" ); document.write( " \n" ); document.write( "c) For another significance test, the newspaper says only that the result was significant at the 1% level. Are such results always, sometimes, or never significant at the 5% level? \n" ); document.write( "Ans: Sometimes If the test meets the 1% significance level it might \n" ); document.write( "or might not meat the 5% significance level. \n" ); document.write( "-------------------------------------------------- \n" ); document.write( " \n" ); document.write( "d) The report claims there is a 95% confidence interval. Would the margin of error in a 99% confidence interval computed from the same data be less, the same, or greater? \n" ); document.write( "Greater because to have the additional level of confidence the interval \n" ); document.write( "would have to be wider. \n" ); document.write( "================================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
