We would like to compare the white cell count (WCC) in a sample of n = 5 patients before and after a treatment.

Subject number WCC Before WCC After

1 111.9 113

2 109 110

3 143 144

4 101 102

5 80 80.9

Is there enough evidence the WCC of the patient is larger after the treatment, at level = 0.05? Give the range of the p-value. (Assume that the difference in WCC is normally distributed.)

(A) yes; P-value < 0.005 (B) yes; 0.005 < P-value < 0.01 (C) yes; 0.01 < P-value < 0.05 (D) no; 0.05 < P-value < 0.10 (E) no; P-value > 0.10
