Find a value of the standard normal random variable z0, with the following probabilities: P(z\n" ); document.write( "---------
\n" ); document.write( "Draw a picture of the normal curve so you can
\n" ); document.write( "understand the answer when you get it.
\n" ); document.write( "-----
\n" ); document.write( "mean = 0
\n" ); document.write( "std = 1
\n" ); document.write( "----
\n" ); document.write( "Plot a z-value on the horizontal axis that has
\n" ); document.write( "a left tail of 0.7497.
\n" ); document.write( "Note that that z-value has area = 0.2497 to the right
\n" ); document.write( "of the mean.
\n" ); document.write( "----
\n" ); document.write( "Now find the area to the left of that z-value.
\n" ); document.write( "====
\n" ); document.write( "I use a TI-84 to get the following::
\n" ); document.write( "invNOrm(0.7497) = 0.6736
\n" ); document.write( "----
\n" ); document.write( "That is the area under the curve to the left of z = 0.7497.
\n" ); document.write( "----
\n" ); document.write( "Cheers,
