Since this is a two-tailed test, we need to divide the alpha level by 2 to get the alpha level for each tail. Thus, for an alpha of .0160, each tail has an alpha of .0080. Looking at the normal distribution table, we can find the z-score that corresponds to an area of .0080 in the tail. We see that the closest value is 2.41, so we circle choice C as the correct answer.
