An article in Nature Genetics studied gene expression as a function of treatments for leukemia. One group received a high dose of the drug, while the control group received no treatment. Expression data (measures of gene activity) from one gene were measured for each group of patients and presented in the box plot. Which statement describes the best interpretation of data based on the box plot? Boxplot of High Dose, Control, Control_1, Control_2 3000- 2500 - 2000 1500 1000- High Dose Control Control 1 Control 2 Oa Those patients receiving high dose of the drug has the lowest measurement of gene activity O b. Patients under control group 2 has the highest mean and greatest dispersion OC All distribution are centered at about the same value but it's apparent that variances differ O d. Further data is needed for patients that received no treatment especially that variances differ as shown in control group 2 Data
