Hello, What I really want to do is to add a rejection region in the form of a long rectangle to a density plot I have drawn. I am getting 2 plots.
How can I add rectangle to first plot? see code below. First section works fine. It just is not quite what I want. # NORMAL DISTRIBUTION PLOT OF RAW DATA WITH UPPER CRITICAL LEVEL - ok xcrit=144.1 # *** single-sample Upper one-tailed hypothesis Test, z statistic *** cord.x <- c(xcrit,seq(xcrit,200,0.01),200) cord.y <- c(0,dnorm(seq(xcrit,200,0.01),140,15),0) curve(dnorm(x,140,15),xlim=c(80,200),main='Normal PDF',ylab="Probability") polygon(cord.x,cord.y,col='orange') # NORMAL DISTRIBUTION PLOT OF RAW DATA WITH UPPER CRITICAL LEVEL - 2 plots? xcrit=144.1 # *** single-sample Upper one-tailed hypothesis Test, z statistic *** curve(dnorm(x,140,15),xlim=c(80,200),main='Normal PDF',ylab="Probability") plot(c(144.1, 200), c(0, .03), type= "n") Thanks.
