Question
05: A. The following are the hemoglobin levels (g/100ml) of a sample of 10 children who
are receiving treatment for a certain disease
6.7, 9.1, 10.0, 11.4, 12.4, 9.8, 8.3, 9.9, 9.1, 7.5
(a) Compare the sample mean and variance.
(b) Suppose you have the following about hemoglobin levels for another sample of 15 healthy
15
children
2r, =150 ,
Ex = 1521
j=1
Determine whether hemoglobin levels of this group are more variable than those of group (a).
