It is not a required reading but it might help you to acquire necessary skills when solving probability questions. Look at the standard normal distribution
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. -3.9.
If your percentile is exactly between two numbers on the table just pick one and move on. 3. Read the ?-value off the side and top of the table. For example
The normal distribution is the most widely known and used of all distributions. Because the normal distribution. Now that we know how to read Table I.
Figure 2: The normal table gives the area under the normal curve to the left of z for Interpretation: 13 is 1.5 standard deviations above the mean for.
Such areas are equivalent to the cumulative probability P(z z0) where z is a standard normal variable and z0 is a fixed value. Section 7.2 shows how to use

standard normal distribution chart How to use the Standard Normal Distribution Table: The standard normal distribution table is shown in the back of your textbook The first column (up and down) of the table represents the number to the left of the decimal of the z-score and the first number to the right of the decimal of z-score
STANDARD NORMAL DISTRIBUTION TABLE Entries represent Pr(Z ? z) The value of z to the first decimal is given in the left column The second decimal is given in the top row DISTRIBUTION TABLE Entries provide the solution to Pr(t > tp) = p where t has a t distribution with the indicated degrees of freedom CHI-SQUARE DISTRIBUTION TABLE
the methods developed using normal theory work quite well even when the distribution is not normal • There is a very strong connection between the size of a sample N and the extent to which a sampling distribution approaches the normal form Many sampling distributions based on large N can be approximated by the normal distribution even
