Normal curve is symmetrical
WebIn geometry, a normal is an object such as a line, ray, or vector that is perpendicular to a given object. For example, the normal line to a plane curve at a given point is the (infinite) line perpendicular to the tangent line to the curve at the point. A normal vector may have length one (in which case it is a unit normal vector) or its length may represent the … Webeach of the following: 1. z=0.96 2. z=1.74 3. z=2.18 4. z=2.69 5. z=3.00 Summary Properties of the Normal Probability Distribution The distribution curve is bell-shaped. The curve is symmetrical about its center. The mean, the median, and the mode coincide at the center. The width of the curve is determined by the standard deviation of the ...
