Here, you want the probability that Z is between –0.5 and 1.0. First, use the Z- table to find the value where the row for –0.5 intersects with the column for 0.00, which is 0.3085. Then, find the value where the row for 1.0 intersects with the column for 0.00, which is 0.8413.

Lesson 7 Z-Scores and Probability Outline Introduction Areas Under the Normal Curve Using the Z-table Converting Z-score to area -area less than z/area greater than z/area between two z-values Formulas and Tables by Mario F. Triola Copyright 2010 ... Formulas and Tables by Mario F. Triola Copyright 2010 Values lecture 13 z scores - Laulima z scores and probability Once you have a z score you can look it up in a table and find out the area between the z score and the mean under the standard normal distribution curve (normal curve). Look at our book. Some z score tables give you the area under the curve between the mean and the z-score.
Z-score is a very useful tool in statistics. It is used in data analysis and deriving meaningful results by calculating the probability of z-scores. If you're having Table 1: Table of the Standard Normal Cumulative Distribution Function Φ(z) z. 0.00. 0.01. 0.02. 0.03. 0.04. 0.05. 0.06. 0.07. 0.08. 0.09. -3.4. 0.0003. 0.0003. When we draw a normal distribution for some variable, the values of the variable are or probability of being selected than scores far away from the mean. the same table to find the areas below the mean corresponding to negative z scores. standard of reference for many probability problems. Z. ~ σ. µ. 2. A table of standardized normal values (Appendix E, Table I) can then be used to obtain an z = b − µ σ and use the table to find the area to the left of the z-value. • For the probability that X>a, convert a into a z-score using z = a − µ.
to this z-score we first look at the row in the table that corresponds to a z-score of 2.1. We then need to look down the column that is headed 0.03. The corresponding P-value is 0.0198. However, this is a two-sided probability and corresponds to the probability that a z-score is either −2.13 or 2.13 (see figure 1). To get the probability
