You are designing a poll to determine the proportion of Oregonians who are in favor of tax cuts. What is the smallest sample size we can use if we want a 98% confidence interval with a margin of error less than or equal to 0.05? (Hint: A 98% confidence interval has critical value z* = 2.326.) 82 3382 2246 542
