Study on New Drug Increasing White Blood Cell Count for Patients on Chemotherapy

Barterol is a drug designed to increase the white blood cell count for patients receiving chemotherapy. When subjects were tested with this drug, their white cell count reading (in thousands per ml) was recorded before and after the drug was taken. The results are shown in the following table. White blood cell counts are normally distributed within a population.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
