Function that computes and draws the area between two user specified values in a user specified normal distribution with a given mean and standard deviation
normarea(lower = -Inf, upper = Inf, m = 0, sig = 1)Arguments
- lower
the desired lower value
- upper
the desired upper value
- m
the mean for the population (default is the standard normal with
m = 0)- sig
the standard deviation of the population (default is the standard normal with
sig = 1)
Value
Draws the specified area in a graphics device
Examples
# Finds and graphically illustrates P(70 < X < 130) given X is N(100, 15)
normarea(lower = 70, upper = 130, m = 100, sig = 15)
