Find positive Z scores in this table. Figure A.2 shows the t distribution with 1 df. Convert X to z-Score Use Unit Normal Table to convert z-score to corresponding percentage/proportion Example Assume a normal distribution with Î¼ = 100 and Ï = 15 What is the probability of randomly selecting an individual with an IQ score less than 130? z 0.000 0.674 0.842 1.036 1.282 1.645 1.960 2.326 2.576 3.090 3.291 0% 50% 60% 70% 80% 90% 95% 98% 99% 99.8% 99.9% Confidence Level t-table.xls 7/14/2007. Appendix E, Table I (Or see Hays, p. 924) reports the cumulative normal probabilities for normally distributed variables in standardized form (i.e. R has two functions that give you values in the z-table. Z-scores). The second decimal place is given in the to â p row.
