You have been studying properties of randomness in general and sampling variability in particular. Through Minitab simulations, you have discovered that sample statistics vary according to a very definite pattern. In this topic you will investigate mathematical models known as normal distributions which describe this pattern of variation very accurately. You will learn how to use normal distributions to calculate probabilities of interest in a vari-ety of contexts
