normalpdf(x [ , m , s] )
Note: For plotting the normal distribution, you can set window variables Xmin and Xmax
so that the mean m falls between them, and then select
0:ZoomFit from the ZOOM menu.
normalcdf( normalcdf( normalcdf( normalcdf(
normalcdf( computes the normal distribution probability between lowerbound and
upperbound for the specified mean m and standard deviation s. The defaults are m=0 and
s=1.
normalcdf(lowerbound,upperbound[,
m
,
s
])
Note: For this example,
Xmin = 28
Xmax = 42
Ymin = 0
Ymax = .2
Xscl = 1
Yscl = .1
