Find the critical value(z alpha\2) needed to construct an 82% confidence interval
\n" ); document.write( "-----
\n" ); document.write( "82% centered on the mean leaves (100-82)/2 = 9% tails on the left and on the right.
\n" ); document.write( "-------
\n" ); document.write( "Left-tail z-value = invNorm(0.09)
\n" ); document.write( "Right-tail z-value = -invNorm(0.09)
\n" ); document.write( "Answer:: -invNorm(0.09) = 1.3408
