Hi all,
I want to add the red color under the standard normal curve to the right
of 1.96.
Can anyone give me a hand? Please see the code below.
Thank you.
x <- seq(-4, 4, length=100)
hx <- dnorm(x)
par(pty="s")
plot(x, hx, type="l", xlab="z value",
ylab="Density", main="density of N(0,1)")
abline(v=1.96, col="red")
