what is probability that mean annual percipitation during 1 randomly selected year will exceed 109.8 inches?
\n" ); document.write( "mean = 107 inches
\n" ); document.write( "standard deviation = 12
\n" ); document.write( "-------------------
\n" ); document.write( "z(109.8) = (109.8-107)/12 = 0.2333
\n" ); document.write( "---
\n" ); document.write( "P(x > 109.8) = P(z > 0.2333) = normalcdf(0.2333,100) = 0.4078
