A 99% confidence intervalhas tobe created to estimate the mean of the volume of contents in the bottles of an expensive medication. How large a simple random samplehas tobe taken so that the margin of error is no more than 5 ml? Assume that the population standard deviation is 20 ml. Consider the following statement for the question numbers 3 and 4. In a simple random sample of 348 likely voters in a large state 54% indicated they would vote for Jim.

State the margin of error of this interval.
