\n" ); document.write( "Compute the z score with x = 4, mu = 5.7 and sigma = 1.5
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " which is approximate to 2 decimal places\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Use a table such as this one to find that \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "note: look on page 1 for the row that starts with -1.1, then look at the column that has 0.03 at the top. This row and column intersect with the value 0.1292 inside\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So this means,
\n" ); document.write( "
\n" ); document.write( " -1.13) = 1-P(Z < -1.13) = 1-0.1292 = 0.8708\">
\n" ); document.write( " -1.13) = 0.8708\">
\n" ); document.write( "This is approximate to four decimal places\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore,
\n" ); document.write( " 4) = 0.8708\">
\n" ); document.write( "which is also approximate\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Final Answer: 0.8708\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "note: this answer is not entirely perfect due to some rounding errors accumulated. Use a calculator (instead of a table) to get more accurate answer. The reason I'm using a table is that a lot of professors require tables as they are found often in the back of your textbook.
