Question

describe a normal probability distribution. (select all that apply.)
mean, median, and mode all equivalent
bell - shaped
uniform - shaped
symmetric around the mean
skewed to the right
most of the data fall within 3 standard deviations from the mean
bimodal
models discrete random variables

Explanation:

• A normal probability distribution is bell - shaped.
• In a normal distribution, the mean, median, and mode are all equivalent.
• It is symmetric around the mean.
• Approximately 99.7% of the data (most of the data) fall within 3 standard deviations from the mean.

Answer:

mean, median, and mode all equivalent, bell - shaped, symmetric around the mean, most of the data fall within 3 standard deviations from the mean.
