How do you determine the proportion of range within a Normal Distribution?
In this video, we dive in to an FE Exam Practice Problem in the subject of PROBABILITY & STATISTICS, specifically revolving around the NORMAL DISTRIBUTION.
What is the NORMAL DISTRIBUTION?
The NORMAL DISTRIBUTION refers to a family of continuous probability distributions that graphically lays out as a BELL CURVE.
The standard NORMAL DISTRIBUTION has an AREA under the CURVE of 1 with a mean of zero and standard deviation of 1.
The NORMAL DISTRIBUTION (or BELL CURVE) is centered at zero and the degree to which a given measurement deviates from the mean is given by the standard deviation.
The NORMAL DISTRIBUTION follows the 68-95-99.7 rule, which says that for a the standard NORMAL DISTRIBUTION, 68% of the observations lie within 1 standard deviation of the mean; 95% lie within two standard deviation of the mean; and 99.9% lie within 3 standard deviations of the mean.
