Q:

Which of the following about the normal distribution is not​ true? (A) ​Theoretically, the​ mean, median, and mode are the same. (B) Its parameters are the​ mean, mu​, and standard​ deviation, sigma. (C) About two thirds of the observations fall withinplus or minus1 standard deviation from the mean. (D) It is a discrete probability distribution.

Accepted Solution

A:
Answer:Normal distribution is a Continuous distribution.Step-by-step explanation:Normal Distribution:The following information is true about normal distribution. ​Theoretically, the​ mean, median, and mode are the same. Its parameters are the​ mean, mu​, and standard​ deviation, sigma. About two thirds of the observations fall within plus or minus 1 standard deviation from the mean.But normal distribution is not a discrete distribution. It is a continuous distribution. The normal distribution is a continuous probability distribution. This has several implications for probability. The probability that a normal random variable X equals any particular value is 0.
