a) Standard Normal curve

Step-by-step explanation:

Characteristics of Normal distribution:-

The Normal curve is bell shaped and symmetrical about the line x=μArea under the Normal curve is unitymean , median and mode of the distribution is coincideThe points of in flexion of the curve are at x =μ±σThe Population two parameters are mean 'μ' and standard deviation 'σ'

The Normal distribution for mean 'μ'=0 and standard deviation 'σ'=1 is Known as Standard  Normal distribution
