Anemia Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to body tissues. People with fewer than $12$grams of hemoglobin per deciliter of blood $(g/dl)$are anemic. A public health official in Jordan suspects that Jordanian children are at risk of anemia. He measures a random sample of $50$children. Check the conditions for carrying out a significance test of the official’s suspicion.

Significance test is a statistical term used to describe a method for making decisions about a population. These decisions will be made based on information contained in a sample taken from within the population being studied.

Through this test method it is possible to obtain evidence that proves or not, a suspicion about that population. For that, it is necessary to know the total number of members in a population, the number of people who, supposedly, would fit into the suspicious situation, and the number of people who really fit into the suspicious situation.

To perform a significance test of the employee's suspicion, you will need:

• Know the total number of children in the community.
• Estimate how many children the employee believes has anemia.
• Determine the correct number of children with anemia.
