Iron-deficiency anemia is an important nutritional health problem in the United States. A dietary assessment was performed on 51 boys, 9 to 11 years of age whose families were below the poverty level. The mean daily iron intake among these boys was found to be 12.50 mg with standard deviation 4.75 mg. Suppose the mean daily iron intake among a large population of 9- to 11-year-old boys from all income strata is 14.44 mg. We want to test whether the mean iron intake among the low-income group is different from that of the general population. a. State the hypotheses. b State the type Land type IL error
