Support conclusion-ferritin distribution smaller variance

Reference no: EM13130960

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

A. No, because the test value 1.60 is less than the critical value of 2.54
B. Yes, because the test value 2.56 is greater than the critical value of 2.54
C. Yes, because the test value 0.390 is less than the critical value 2.54
D. Yes, because the test value 2.56 is greater than the critical value 0.394
