Q1) Serum ferritin is utilized in diagnosing iron deficiency.  In study conducted recently researchers discovered that in 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?

a) No, as the test value 1.60 is less than critical value of 2.54         

b) Yes, as the test value 2.56 is greater than critical value of 2.54

c) Yes, as the test value 0.390 is less than critical value 2.54

d) Yes, as the test value 2.56 is greater than critical value 0.394
