Question 756286: Assume that a random sample is used to estimate a population p. Find the margin of error E that corresponds to the given statistics and confidence level.
95% confidence the sample size is 1443 of which 35% are successes
The margin of error E= round 4 decimals as needed

Assume that a random sample is used to estimate a population p. Find the margin of error E that corresponds to the given statistics and confidence level.
95% confidence the sample size is 1443 of which 35% are successes
-------
E = z*sqrt[pq/n]
----
E = 1.96*sqrt[0.35*0.65/1443]= 0.0246
