A 95% confidence interval requires a larger margin of error. In order to increase confidence, the interval must be narrower A 95% confidence interval requires a larger margin of error. In order to increase confidence, the interval must be wide A 95% confidence interval requires a smaller margin of error. In order to decrease confidence, the interval must be wider A confidence interval requires a smaller margin of error. In order to decrease confidence, the interval must be arrowes. (d) Find the margin of error for 95% confidence (Use 4 decimals) () Which part of the confidence interval was affected when the confidence level was changed? sample statistic standard error Critical value
