Select the statements that describe a normal distribution.

a. the density curve is symmetric and bell‑shaped.
b. the normal distribution is a continuous distribution.
c. the normal distribution is a discrete distribution.
d. the density curve is a flat line extending from the minimum value to the maximum value.

approximately 32% of values fall more than one standard deviation from the mean.
two parameters define a normal distribution—the median and the range.

The statements that describe a normal distribution are;

a. The density curve is symmetric and bell-shaped.

b. The normal distribution is a continuous distribution.

Step-by-step explanation: The normal distribution is the most commonly used and important statistic tool. It is referred to as the "Bell Curve" because of its bell-shape and the the fact that it is symmetric density curve. A continuous distribution defines the possibilities of a continuous random variable and a prime example of a continuous distribution is the Normal distribution.

The normal distribution is not a discrete distribution because it does not have discrete variables. The normal distribution is not a flat line that extends from a minimum to a maximum but it is a continuous distribution that extends in a bell shape from one minimum value going up to a maximum value before descending back to another minimum value.

68% of a normal distribution curve falls with one standard deviation from the mean not 32%.

The two parameters that define a normal distribution is the mean and the standard deviation.

man its nopq i just guessed and got it right so uhh
