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 : -1.76/<1-2<-1.62/.

Required:
What does the confidence interval suggest about equality of the mean hemoglobin level in women and the mean hemoglobin level in men?
