The normal distribution curve is symmetrical about: (a) X=mu (b) X=sigma (c) X=(mu)/(0) (d) X=(sigma)/(mu)
Answers
Answer:
his means that the distribution curve can be divided in the middle to produce two equal halves. The symmetric shape occurs when one-half of the observations fall on each side of the curve.
Step-by-step explanation:
Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean. In graph form, normal distribution will appear as a bell curve.
The curve is symmetrical about a vertical line drawn through the mean, μ. In theory, the mean is the same as the median, because the graph is symmetric about μ. ... This means there are an infinite number of normal probability distributions. One of special interest is called the standard normal distribution.
