![]() The dividends paid by a company every year are normally distributed with a mean of $10 and a standard deviation of $2. In the above table, F(Z) is the probability that a variable from a standard normal distribution will be less than or equal to Z. The following z-table shows the probabilities for z values ranging between – 3 and 3. The standard normal table shows the area (as a proportion, which can be translated into a percentage) under the standard normal curve corresponding to any Z-score or its fraction, i.e., the probability of observing a z-value that is less than the given value. ![]() Once we have the z-scores, we can use the standard normal table to calculate the probabilities.
