Using R Studio,

Generate a standard normal random. using rnorm()

Check whether this number is >1.96 or <-1.96.

Replicate this 1000 times and count the number of observations that are greater than 1.96 or less than -1.96.

Calculate the ratio of this number to the the number of replications and see whether this is close to 0.05.

HINT:

num <- 0

for (i in 1 : 1000) {

+a <-

+

}

num/1000
