This section presents the standard normal distribution which has three properties: 1 It is bell-shaped 2 It has a mean equal to 0 3 It has a standard
Suppose our experiment is to toss a single fair die, and we are interested in the number rolled We define our random variable X to be
Def A continuous random variable has a normal distribution if its density curve is symmetric and bell-shaped Specifically, the curve is given by: ( )2 2 1
The normal probability plot suggests that the data appear to be right-skewed The kurtosis is 0 5395 indicating a distribution that is slightly more peaked than
