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

does not include
