You can put this solution on YOUR website!
the two outside areas are each equal to .02 of the normal distribution curve.
\n" ); document.write( "find he z-score that has an area to the left of it equal to .02.
\n" ); document.write( "find the z-score that has an area to the right of it equal to .02.
\n" ); document.write( "note that the z-score that has an area of .02 to the right of it will be equal to the z-score that has an area of .98 to the left of it (.98 = 1 minus .02).
\n" ); document.write( "the area between those z-scores will be equal to .96
\n" ); document.write( "you can do this manually through the tables, or you can use a calculator.
\n" ); document.write( "calculator is much easier.
\n" ); document.write( "i used the following calculator.
\n" ); document.write( "https://davidmlane.com/hyperstat/z_table.html
\n" ); document.write( "using this calculator, i found the z-score with .02 area to the left of it equal to -2.054 and i found the z-score with .02 area to the right of it equal to 2.054.
\n" ); document.write( "those same z-score gave me an area between them of .96.
\n" ); document.write( "here are the displays of my use of the calculator.
\n" ); document.write( "first is finding the z-score with area of .02 to the left of it.
\n" ); document.write( "second is finding the z-score with area of .02 to the right of it.
\n" ); document.write( "this is finding the z-scores with area of.96 between them.\r
