Area from a value (Use to compute p from Z) Value from an area (Use to compute Z for confidence intervals). Specify Parameters:  http://www.stat.ufl.edu/~athienit/Tables/Ztable.pdf. There is also a z table in the back of any statistics book. ANSWER: First, let's look at what we are given in the 

Table of z values and probabilities for the standard normal distribution. z is the Probability. Distribution: P. (x. ) = λ x e− λ x ! Chapter. 6: Normal. PDF: f(x. ) The following graph shows 102 observations and the resulting regression line. Notice . 'How a value 'X' from a normal distribution is converted into z-score? of a given value 'X' at the subdivision of -3, -2,-1,0,1,2,3 by looking at the graph. However  Example 2: Find probability that Z is between 0 and 0.82 or P(0

To use the z-score table, start on the left side of the table go down to 1.0 and now at the top of the table, go to 0.00 (this corresponds to the value of 1.0 + .00 = 1.00). The value in the table is .8413 which is the probability. Negative Z score table Use the negative Z score table below to find values on the left of the mean as can be seen in the graph alongside. Corresponding values which are less than the mean are marked with a negative score in the z-table and respresent the area under the bell curve to theContinue Reading STATISTICAL TABLES. 1 TABLE A.1 Cumulative Standardized Normal Distribution. A(z) is the integral of the standardized normal distribution from −∞to z (in other words, the area under the curve to the left of z). It gives the probability of a normal random variable not being more than z standard deviations above its mean. Note that the probabilities given in this table represent the area to the LEFT of the z-score. The area to the RIGHT of a z-score = 1 – the area to the LEFT of the z-score Title If you noticed there are two z-tables with negative and positive values. If a z-score calculation yields a negative standardized score refer to the 1st table, when positive used the 2nd table. For George’s example we need to use the 2nd table as his test result corresponds to a positive z-score of 0.67.

For a given value of Z, the table reports what proportion of the distribution lies below that value.

Calculate Z score using these negative and positive Z score tables based on normal bell shaped distribution.

Cumulative probabilities for POSITIVE z-values are shown in the following table: Title: std normal table.xls Created Date: 4/23/2009 3:32:38 AM To use the z-score table, start on the left side of the table go down to 1.0 and now at the top of the table, go to 0.00 (this corresponds to the value of 1.0 + .00 = 1.00).
