What is the shape of the Normal distribution?Question 3Answera.bell curveb.squarec.rectangular

1. Break Down the Problem

The question asks for the shape of the Normal distribution and provides multiple choices. We need to identify the correct option.

2. Relevant Concepts

The Normal distribution, also known as Gaussian distribution, is a probability distribution that is symmetric about the mean.

3. Analysis and Detail

• The Normal distribution is often represented graphically as a bell-shaped curve.
• It has two main characteristics: it is symmetric around the mean, and it tapers off towards the extremes.

4. Verify and Summarize

Among the choices provided:

• a. bell curve: This describes the shape accurately.
• b. square: This does not correspond to any known distribution.
• c. rectangular: This is also incorrect for a Normal distribution.

Final Answer

The shape of the Normal distribution is best described as a bell curve (answer a).
