1. If 90 working age women are randomly selected, what is the probability that between 58% and 73.6% are in the labor force? Be sure to use the Empirical Rule and not exact values, and round your z-scores to the nearest whole number. Round your answer to 4 decimal places. 2. If 170 working age women are randomly selected, what is the probability that between 58% and 61.8% are in the labor force? Be sure to use the Empirical Rule and not exact values, and round your z-scores to the nearest whole number. Round your answer to 4 decimal places. 3. What happens to the standard error as the sample size increases?
