During a national debate on changes to health care, a cable news service performs an opinion poll of 500 small business owners. It shows that 65% of small-business owners do not approve of health care changes. Develop a 95% confidence interval for the proportion opposing health care changes. Use 4 decimal places.

Question 6 View Policies Current Attempt in Progress 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 90% confidence interval for p given that p = 0.34 and n = 500. wers for the margin of error and the confidence interval Round your answer for the best...

Question 11 View Policies Current Attempt in Progress Use the t-distribution to find a confidence interval for a mean given the relevant sample results. Give the best point estimate for the margin of error, and the confidence interval. Assume the results come from a random sample from a population that is approximately normally distributed. A 90% confidence interval for using the sample results T = 3.2.5 = 0.2, and n = 100 Round your answer for the point estimate to...

Estimators are used in two different ways: point estimation and confidence estimation.
(36) Estimators are used in two different ways: point estimation and confidence estimation. (1) True. (2) False. (37) Which of the statements about large-sample estimation is correct? (1) An estimator should be unbiased and the spread (as measured by the mean) should be as small as possible. (2) The distance between an estimate and the true value of the statistic is called the error of estimation. (3) The 95% Margin of error is: 1.96 x Standard error of the estimator. (4) A good confidence interval is as...
