a. Why does"margin oferror" have no relevance for confidence interval estimates of or 2?

b. What is wrong with expressing the confidence interval of 7.4 bpm<<14.4 bpm as 10.9 bpm3.5 bpm?

a. Choose the correct answer below.

A.Unlike confidence interval estimates of p or , confidence interval estimates of or 2 are created using a distribution that issymmetric, so there is no "E" as in confidence interval estimates of p or .

B.Like confidence interval estimates of p or , confidence interval estimates of or 2 are not created using a distribution that issymmetric, so there is no "E" as in confidence interval estimates of p or .

C.Unlike confidence interval estimates of p or , confidence interval estimates of or 2 are not created using a distribution that issymmetric, so there is no "E" as in confidence interval estimates of p or .

D.Like confidence interval estimates of p or , confidence interval estimates of or 2 are created using a distribution that issymmetric, so there is no "E" as in confidence interval estimates of p or .

b. Choose the correct answer below.

A.Expressing the interval as 10.9 bpm3.5 bpm is misleading because it is larger than the actual interval of 7.4 bpm<<14.4.

B.Expressing the interval as 10.9 bpm3.5 bpm is misleading because it implies that point estimate for is s=10.9 bpm, which is not true.

C.Expressing the interval as 10.9 bpm3.5 bpm is misleading because it is smaller than the actual interval of 7.4 bpm<<14.4.

D.Expressing the interval as 10.9 bpm3.5 bpm is misleading because it implies that point estimate for is s=3.5 bpm, which is not true.
