B
OOOO
D

Answer 1

a) Standard Normal curve

Explanation:

Characteristics of Normal distribution:-

• The Normal curve is bell shaped and symmetrical about the line x=μ
• Area under the Normal curve is unity
• mean , median and mode of the distribution is coincide
• The points of in flexion of the curve are at x =μ±σ
• The 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
