Find the standard normal probabilities of being less than the following z-scores. Compare the probabilities found in the normal distribution table to the values found using the calculator with the normalcdf function. There is a link to the normal tables in Course Documents; these are the "official" tables used by U.S. government agencies. But there is a more convenient, user-friendly table in the "formula card", available as a .pdf file (also in Course Documents). Z-Score 155 1.4 1.96 -1.4 -1.28 -.82 From Table From Calculator
