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.

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

b. A brief statement that interprets that confidence interval.

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