Areas Under Normal Curve. What is the area under the curve. Find the area under the standard normal curve to the right of z -267. To the right of Z. The table of areas of normal probability curve is then referred to find out the proportion of area between the mean and the Z value.
Find the area under the standard normal curve between z -181 and z 126. This table shows the area between zero the. Let A area then use Table II. You can also use the table below. Let A area then from Table II. The table of areas of normal probability curve is then referred to find out the proportion of area between the mean and the Z value.
Since the normal curve is symmetric about the mean the area on either sides of the mean is 05 or 50.
In mathematics the bell-shaped curve that is typical of the normal distribution. Find the Indicated Area Between Two Values. To answer this question we simply need to subtract the area to the left of z -181 from the area to the left of 126. How to find area under normal distribution curve. For example often we might want to indicate whether an absolute value is greater than 2. The area under the standard normal curve to the right of z -181 is 1 0351 09649.
