Use the normal distribution to find a confidence interval for a proportion p given the relevant sample results. Give the best point estimate for p , the margin of error, and the confidence interval. Assume the results come from a random sample. A 95% confidence interval for the proportion of the population in Category A given that 18% of a sample of 450 are in Category A. Round your answer for the point estimate to two decimal places, and your...

To calculate a confidence interval, the margin of error (E) must first be calculated. The Margin of Error, E, for means is: E = 1.96*s/sqrt(n), where s is the sample standard deviation, n is the sample size. The “sqrt” stands for square root. The Margin of Error, E, for proportions is: E = 1.96*sqrt[p*(1-p)/n], where s is the sample standard deviation, n is the sample size, and p is the proportion. Use the Confidence Interval formula above, and the correct...

3. Question 3 Aa Aa E A confidence interval estimate is an estimate of a population parameter providing an interval that is believed (with a certain level of confidence) to contain the value of the population parameter. The confidence level is the level of confidence associated with the confidence interval estimate. If your confidence level is 94%, then if you were to employ repeated sampling and compute the confidence interval estimate for each sample, you would expect % of the...
