How would you describe the effect that doubling the sample size would have on the width of a one-proportion confidence interval, if the confidence level and sample proportion remain the same? The new interval would be about one-fourth the size of the previous interval. The new interval would be about half the size of the previous interval. The new interval would be about 70% the size of the previous interval. The new interval would be about 140% the size of the previous interval. The new interval would be about double the size of the previous interval.
