Full Z Table Math
Z score 800 700 180.
Full z table math. Z score x µ σ. Because the z table gives you only less than probabilities subtract p z 1 5 from 1 remember that the total probability for the normal distribution is 1 00 or 100. Table values represent area to the left of the z score. 0 1 53983 54380 54776 55172 55567 55962 56356 56749 57142 57535.
Z score observed value mean of the sample standard deviation. Use the z table to find where the row for 1 5 intersects with the column for 0 00 which is 0 9332. The z table on this page indicates the area to the right of the vertical center line of the z curve or standard normal curve for different standard deviations. Z 00 01 02 03 04 05 06 07 08 09 0 0 50000 50399 50798 51197 51595 51994 52392 52790 53188 53586.
This table is very useful for finding probabilities when the event in question follows a normal distribution. To find out the z score we use the formula.
