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<?1??2<?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?
