15. The leader of your campaign does not think your results are accurate enough. She wants you to take a new sample, and this time she wants you to be 95% sure that the sample proportion is within .03 of the actual population proportion of California voters who plan to vote for the proposition. Based on your previous sample, you now have a planning value for p. Use this value as p* and calculate how many California voters you need to include in your new sample in order to meet the campaign leader's requirement.
