ShadeNorm(
ShadeNorm( draws the normal density function specified by mean m and
standard deviation s and shades the area between lowerbound and
upperbound . The defaults are m =0 and s =1.
ShadeNorm( lowerbound , upperbound [ ,

,
s ] )
Note: For this example,
Xmin = 55
Xmax = 72
Ymin =
L .05
Ymax = .2
Shade_t(
Shade_t( draws the density function for the Student- t distribution specified
by df (degrees of freedom) and shades the area between lowerbound and
upperbound .
