Algebra.Com's Answer #538011 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! I'm working on a probabilities question concerning the central limit theorem. The course is showing me the steps: \n" ); document.write( " Let mu x_bar represent the mean of the distribution. \n" ); document.write( "mu x-bar = mu = 9.6 \n" ); document.write( " Correct! Good job! \n" ); document.write( "================================== \n" ); document.write( " Step 2: \n" ); document.write( "Let sigma x=bar represent the standard deviation of the x-bar distribution. \n" ); document.write( "sigma x-bar = sigma/sqrt(n) = 1.2\r \n" ); document.write( "\n" ); document.write( "I get to step 2 which should say sigma x(bar) times the square root of the sample number or 1.2 time the square root of 5. every time I enter this into my calculator i get 2.68 but they say the answer is 0.54. What am I doing wrong? \n" ); document.write( "-------- \n" ); document.write( "Comment:: You did not post the original Step 2 problem. \n" ); document.write( "I guess you are asked to find sigma if n = 5. \n" ); document.write( "If so, sigma = 1.2*sqrt(5) = 2.68 \n" ); document.write( "================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "--------------- \n" ); document.write( " |
