    MATH 140 - Introduction to Statistics 1.36 2] Researchers examined a new treatment for advanced ovarian cancer in a mouse model. They created a nanoparticle-based delivery system for a suicide gene therapy to be delivered directly to the tumor cells. The grafted tumors were injected either with the new treatment or with only some buffer solution to serve as a comparison. The data below give the fold increase in tumor size after two weeks in 20 mice. A 1 represents...
