Unformatted text preview: 0.4 Distribution of Normal distribution with mean = 0 and variance = 1 y F(y)42 2 4 0.6 0.8 1.0 The theoretical mean of the normal distribution is = E ( Y ) = The variance of the normal distribution is 2 = V ( Y ) = 2 The normal distribution is very important in statistical theory and we will be learning much more about this distribution in Statistics 342. Working with normal random variables in R. To Fnd the probability P ( Y y ) the command in R is pnorm(y,mu,sigma) 1 To fnd the value oF y so that P ( Y y ) = p the command in R is qnorm(p,mu,sigma) To generate observed values From a normal distribution the command in R is rnorm(numobs,mu,sigma) where numobs is the number oF observed values you would like to generate. 2...
