2.4.2 The Normal distribution (A-level only)

Card 1 of 23

How is probability represented on a Normal curve?

A

By the area under the curve, not its height.

B

P(X>a)=1−P(X<a)P(X>a)=1-P(X<a)P(X>a)=1−P(X<a).

C

If XXX is Normally distributed, its notation is X∼N(μ,σ2)X\sim N(\mu,\sigma^2)X∼N(μ,σ2), where the second parameter is the variance.

D

It moves the entire curve to the right.
