if the population has a M = 500 and SD = 200 what is the probability of selecting a sample with a mean of >590 ? <390 ?
\n" ); document.write( "p(M>590)
\n" ); document.write( "----
\n" ); document.write( "z(590) = (590-500)/[200/sqrt(n)] = ?
\n" ); document.write( "Question: What is the sample size?
\n" ); document.write( "----------
\n" ); document.write( "p(M<390)
\n" ); document.write( "z(390) = (390-500)/[200/sqrt(n)] = ?
\n" ); document.write( "Question: What is the sample size
