Question

the normal curve quick check
which of the following lists the criteria for using a normal curve as a model for a distribution? (1 point)
the distribution is bell - shaped, the standard deviation is in the center of the data, and the data values follow the empirical rule.
the data values follow the empirical rule, the standard deviation is in the center of the data, and the distribution is skewed to the left or right.
the data values follow the empirical rule, the mean is in the center of the data, and the distribution is bell - shaped.
the distribution is bell - shaped, the mean and the standard deviation are approximately equal and in the center of the data, and the data values follow the empirical rule.

Explanation:

• A normal distribution is bell - shaped.
• The mean is at the center of the data in a normal distribution.
• The data values in a normal distribution follow the Empirical Rule (about 68% of data within 1 standard deviation of the mean, about 95% within 2 standard deviations, and about 99.7% within 3 standard deviations).

Answer:

The data values follow the Empirical Rule, the mean is in the center of the data, and the distribution is bell - shaped.
