Standard Normal Cumulative Probability Table Cumulative probabilities for NEGATIVE z-values are shown in the following table:
Here is the data behind the bell-shaped curve of the Standard Normal Distribution
To find out the Z score we use the formula. Z Score = (Observed Value – Mean of the Sample)/standard deviation. Z score = ( x – µ ) / σ. Z score = (800-700) / 180. Z score = 0.56.
STANDARD NORMAL DISTRIBUTION: Table Values Represent AREA to the LEFT of the Z score. Z .00 .01 .02 .03 .04 .05 .06 .07 .08 .09 0.0 .50000 .50399 .50798 .51197 .51595 ...
t DISTRIBUTION TABLE Entries provide the solution to Pr(t > t p) = p where t has a t distribution with the indicated degrees of freedom.
In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution.
A Z-score table, also called the standard normal table, or z-score chart, is a mathematical table that allows us to know the percentage of values below (usually a decimal figure) to the left of a given Z-score on a standard normal distribution (SND).
Standard Normal Distribution Tables STANDARD NORMAL DISTRIBUTION: Table Values Re resent AREA to the LEFT of the Z score. -3.9 -3.8 -3.6 -3.5
Z is the standard normal random variable. The table value for Z is the value of the cumulative normal distribution. For example, the value for 1.96 is P(Z<1.96) = .9750. Find the p-value using the standard normal table.
