Example 3:

Suppose that after graduating from UF you decide to volunteer as a biostatistician in socioeconomically disadvantaged areas of Miami-Dade county. Many of the children appear pale and may be suffering from anemia. People with less than 12 grams of hemoglobin per dL of blood are considered anemic. You saw 36 children and observe the following statistics:

m = 11.3 g/dL, s = 1.5g/dL.

a. Calculate the 95% and 99% confidence intervals for both mean and

standard deviation.

b. Comment on your findings relative to the standard definition of

anemic
