Quizplus · Accepted Answer

For a two-tailed test at a .0694 level of significance, the significance level is split between the two tails of the normal distribution, so each tail has .0347 (which is .0694/2). Looking up .0347 in the z-table (or using a calculator or software that provides z-values for given tail probabilities) gives a z-value close to ±1.48.
