Why does "margin of error" have no relevance for confidence interval estimate of or ^2? A. Unlike confidence interval estimates of p or u, confidence interval estimates of or ^2 are not created using a distribution that is symmetric, so there is no "+ or - E" as in confidence interval estimates of p or u. B. Unlike confidence interval estimates of p or u, confidence interval estimates of or ^2 are created using a distribution that is symmetric, so there is no "+ or - E" as in confidence interval estimates of p or u. C. Like confidence interval estimates of p or u, confidence interval estimates of or ^2 are created using distribution that is symmetric, so there is no "+ or - E" as in confidence interval estimates of p or u. D. Like confidence interval estimates of p or u, confidence interval estimates of or ^2 are not created using a distribution that is symmetric, so there is no "+ or - E" as in confidence interval estimates of p or u. What is wrong with expressing the confidence interval of 6.7 bpm << 13.9 bpm as 10.3 bpm + or - 3.6 bpm? A. Expressing the interval as 10.3 bpm + or - 3.6 bpm is misleading because it implies that point estimate of is s= 3.6 bpm, which is not true. B. Expressing the interval as 10.3 bpm + or - 3.6 bpm is misleading because it implies that point estimate for is s= 10.3 bpm, which is not true. C. Expressing the interval as 10.3 bpm + or - 3.6 bpm is misleading because it is smaller than the actual interval of 6.7 bpm < < 13.9. D. Expressing the interval as 10.3 bpm + or - 3.6 bpm is misleading because it is larger than the actual interval of 6.7 bpm < < 13.9
