Question 9 • SC-Statistical Modeling
A 94% confidence interval leaves 6% outside the center, split into 3% in each tail. The cumulative area to the left of the positive critical value is therefore 1 − 0.03 = 0.97. The z-score for a cumulative area of 0.97 is about 1.88, so the correct choice is 1.88.
