      Finding areas under this curve is hard, so we rely on a table of such values. The problem is that it is impossible to have a table that would give us areas for each possible mean and standard deviation. The table is the z-table and it has a normal shape, with a very nice mean, namely ____, and a very nice standard deviation, namely _____(why ...

      Probabilities associated with the normal curve correspond to areas under the curve. The total area under the curve is 1 (i.e. 100%). The probability of a particular point is 0 (since no associated area above a point). Most of the values lie towards the center of the curve with the arithmetic mean, median, and mode lying at its very center.

      This is done with the standard normal tables in the book. Table A is a table of areas under the standard normal curve. The table entry for each value z is the area under the curve to the left of z. Figure The area under a standard normal curve to the left of the point z=1.40 is 0.9192. Figure The area under a standard normal curve to the right ...

      Finding Areas Under the Normal Curve. 1) We can easily find areas like the one below. First, find the distance that xi is from the mean and then divide this distance by the size of the standard deviation. The result will be. Look up the area in the Z-table.

      The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1. Recall: z Values. The z value is the number of standard deviations that a particular X value is away from the mean. The formula for finding the z value is: Finding Areas Under the Standard Normal Distribution Curve . Area To the Left of Any ...
