True

True

True.

To answer this question, we need to understand what a normal distribution is and what its graph looks like.

A normal distribution, also known as a Gaussian distribution, is a probability distribution that is symmetric and bell-shaped. It is characterized by its mean (center) and standard deviation (spread). In a normal distribution, the majority of the data points cluster around the mean, with fewer data points further away from the mean.

To visualize a normal distribution, we can plot a graph. The x-axis represents the values of the variable being measured, while the y-axis represents the frequency of occurrence for each value. The graph will have a bell-shaped curve, with the peak at the mean and the tails extending towards both ends symmetrically.

So, to answer the question, "The graph of a normal distribution is bell-shaped," the answer is true.
