On a standard measure of hearing ability, the mean is 300 and the standard deviation is 20. \r
\n" ); document.write( "\n" ); document.write( "Give the Z scores for persons who score \r
\n" ); document.write( "\n" ); document.write( "(a) 340, (b) 310,(c) 260.
\n" ); document.write( "You are given the raw scores (x)
\n" ); document.write( "You can find the z-score using the formula
\n" ); document.write( "z = (x-u)/sigma
\n" ); document.write( "Example:
\n" ); document.write( "z(340) = (340-300)/20 = 40/20 = 2
\n" ); document.write( "Do the same for x = 310 and for x = 260
\n" ); document.write( "===============================================\r
\n" ); document.write( "\n" ); document.write( "Give the raw scores for persons whose Z scores on this test are (d) 2.4,
\n" ); document.write( "(e) 1.5, (f) 0, and (g)-4.5.
\n" ); document.write( "You are given the z-scores (z)
\n" ); document.write( "You can find the raw scores (x) using the formula
\n" ); document.write( "x = zs + u
\n" ); document.write( "Example
\n" ); document.write( "If z = 1.5, x = 1.5*20 + 300
\n" ); document.write( "x = 30 + 300
\n" ); document.write( "x = 330
\n" ); document.write( "===================================
