Question

The total area under normal distribution curve is
a) Less than 1, b) 1, c) More than 1, d) Between -1 and 1

Answer 1

The total area under the normal curve is equal to 1

Answer 2

• A normal distribution curve is a continuous probability distribution graph.
• It is a bell-shaped curve.
• The normal distribution curve is symmetric about the mean i.e., out of total area 50% lie on the left side of mean and 50% lie on the right side of mean in normal distribution curve graph.
• It is important in statistics.
• The total area under the normal distribution curve is equal to 1 or 100%
