Question 924081: The market researcher’s boss would like a more precise (narrower) confidence interval than the one reported in Q 6. What are two things the market researcher might choose to do to make the confidence interval narrower? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! ME = z (sd/sqrt(n)
ME less...(making the confidence interval narrower)
1. Increase sample size
2. decrease critical value (Use 95% confidence Level vs 99% confidence level, for ex)
