Refer to the serum lipid-bound sialic acid data on 1400 subjects (LSADATA). We wish to conduct a study to determine if the measurement of serum lipid-bound sialic acid (LSA) might be of use in the detection of breast cancer. The LSA measurements (mg/dl) are for four populations of subjects: normal controls, A; patients with benign breast disease, B; patients with primary breast cancer, C; and patients with recurrent metastatic breast cancer, D. Select a simple random sample of size 10 from each population and perform an appropriate analysis to determine if we may conclude that the four population means are different. Let a ¼ :05 and determine the p value. Test all possible pairs of sample means for significance. What conclusions can one draw from the analysis? Prepare a verbal report of the findings. Compare your results with those of your classmates.
