Transcribed Image Text:K
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 g/dL <H₁ H2 -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?
Because the confidence interval
appears that there
a significant difference between the
mean level of hemoglobin in women and the mean level of
hemoglobin in men.
