Find the area in the left tail calculator
WebFeb 16, 2024 · To find the area to the right of a positive z-score, begin by reading off the area in the standard normal distribution table. Since the total area under the bell curve is 1 (as a decimal value which is equivalent to 100%), we subtract the area from the table from 1. For example, the area to the left of z = 1.09 is given in the table as .8621. http://courses.atlas.illinois.edu/spring2024/STAT200/pnormal.html
