Large samples of women and men areobtained, and the hemoglobin level is measured in each subject. Here is the95% confidence interval for the difference between the two populationmeans, where the measures from women correspond to population 1 and the measures from men correspond to population2: 1.76g/dL<12<1.62g/dL. Complete parts(a) through(c) below.

a. What does the confidence interval suggest about equality of the mean hemoglobin level in women and the mean hemoglobin level inmen?

Because the confidence interval includes, does not include or nothing, it appears that there ,is not or is a significant difference between the mean level of hemoglobin in women and the mean level of hemoglobin in men.

b. Write a brief statement that interprets that confidence interval.

A.

There is95% confidence that the interval from 1.76 g/dL to 1.62 g/dL does not contain the value of the difference between the two population means 12.

B.

There is95% confidence that the difference between the two population means is not 0.

C.

There is95% confidence that the interval from 1.76 g/dL to 1.62 g/dL actually contains the value of the difference between the two population means 12.

D.

There is95% confidence that the difference between the two population means 12 is either 1.76 g/dL or 1.62 g/dL.

c. Express the confidence interval with measures from men being population 1 and measures from women being population 2. Choose the correct answer below.

A.

1.76g/dL<12<1.62g/dL

B.

1.76g/dL<12<1.62g/dL

C.

1.62g/dL<12<1.76g/dL

D.

1.62g/dL<12<1.76g/dL
