Serum ferritin is used in diagnosing iron deficiency. In the study conducted recently researchers discovered that in the sample of 28 elderly men sample standard deviation of serum ferritin was 52.6 mg/L. For 26 younger men sample standard deviation was 84.2 mg/L. At .01 level of significance, do these data support conclusion that ferritin distribution in elderly men has smaller variance than in younger men?
