WebRnorm () Rnorm generates random numbers that are normally distributed. We use the random numbers and plot them on the histogram to show normally distributed numbers. Syntax: rnorm (n, mean, sd) mean-mean value of the data. The default value is zero. sd-standard deviation. The default value is 1. p is a set of probabilities. Code: WebFor each probability distribution there are typically four functions available that start with a “r”, “d”, “p”, and “q”. The “r” function is the one that actually simulates randon numbers from that distribution. The other functions are prefixed with a. d for density; r for random number generation; p for cumulative distribution
