2. According to the World Health Organization, iron deficiency is the most common nutritional deficiency worldwide. Iron is a component of hemoglobin, a protein found in red blood cells (RBCs) that carries oxygen from the lungs to the tissues. Low levels of iron may cause iron deficiency anemia, where fewer healthy RBCs are present. Fermium tablets (containing 100 mg of iron/tablet) are an iron supplement that is used to improve anemia and overall iron status. Here we will consider total iron binding capacity (TIBC, mcg/dL) as an indirect measure of iron status. TIBC is higher than normal when body's iron supplies are low and, conversely, TIBC is lower than normal when iron supplies are high. We are curious about whether Fermium tablets improve overall iron status (i.e., TIBC) and have the following results to examine the association. (20 points total / 4 points each) Coef. Std.

If a randomly selected woman of childbearing age took 10 more tablets of Fermium than her neighbor, what is the best prediction for their difference in TIBC? d. What does the _cons indicate? e.
