Large samples of women and men are obtained, and the hemoglobin level is measured in each subject. here is the 95% confidence interval for the difference between the two population means, where the measures from women correspond to population 1 and the measures from men correspond to population 2:
negative 1.76 g divided by dl less than mu 1 minus mu 2 less than minus 1.62 g divided by dl
−1.76 g/dl< μ1−μ2< −1.62 g/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 in men?
