For the interval (0.051, 0.074) for estimating p, based on a sample of size n = 1120, determine the margin of error:
Solution :
Point estimate =
= (Lower confidence interval + Upper confidence interval) / 2
= 0.0625
Margin of error = E = Upper confidence interval -
=
= 0.074 - 0.0625
= 0.0115

Question 2 2 pts Assume that a sample is used to estimate a population proportion p. Find the margin of error E that corresponds to the given statistics and confidence level. Round the margin of error to four decimal places. 90% confidence; n 390, x-146
Recall the formula for a proportion confidence interval is p^?zp^(1?p^)n?????????<p<p^+zp^(1?p^)n????????? Thus, the margin of error is E=zp^(1?p^)n????????? . NOTE: the margin of error can be recovered after constructing a confidence interval on the calculator using algebra (that is, subtracting p^ from the right endpoint.) In a simple random sample of size 59, taken from a population, 20 of the individuals met a specified criteria. a) What is the margin of error for a 90% confidence interval for p, the population...
