6. White blood cell counts are helpful for assessing liver disease, radiation, bone marrow failure, and infectious diseases. Listed below are white blood cell counts found in simple random samples of males and females. Assume that the two populations are normal. Female: 8.90 6.50 9.45 7.65 6.40 5.15 16.60 5.75 11.60 4.05 9.05 5.90 9.30 8.55 10.80 4.85 4.90 8.75 6.90 9.75 5.05 6.40 4.05 7.60 4.95 3.00 9.10 Male: 5.25 5.95 10.05 5.45 5.30 5.55 6.85 6.65 6.30 6.40 7.85 7.70 5.30 6.50 4.55 7.10 8.00 4.70 4.40 4.90 10.75 11.00 4.70 Construct a 95% condence interval estimate of the difference between the mean blood cell counts for females and the mean blood cell counts for males. What does the condence interval suggest
