256 QUESTION 16 From Case Study 3 Tumors, which of the following statements best expresses the null hypothesis for this experiment.(1 pt Case Study (questions #14-120): A scientist wishes to know if a certain drug inhibits the growth of tumors (ie, decreases tumor mass). She obtained mice with turmors and randomly divided them into two equal groups. Mice ir Group A served as the control and did not receive doses of the drug, while mice in Group B received regular doses of the drug. After 2 weeks of treatment, she sacrificed all the mice, resected the tumors and determined the mass of each tumor. The mass of the tumor taken from each mouse is given below. Using Microsoft Excel, perform an appropriate statistical test to evaluate the data and answer questions #14-12. Tumor Mass (grams) Mouse Number Group A Group B 0.71 0.83 0.89 0.57 0.72 0.68 0.69 0.66 0.74 0.75 0.67 0.70 0.63 0.71 0.73 0.675 10 0.78 0.742 O There is no significant difference in the average tumor mass from the two groups of mice. O There is a significant difference in the average tumor mass from the two groups of mice O The average tunor mass of Group A mice will be significantly less than that of Group B The average tunor mass of Group B mice will be significantly less than that of Group A QUESTION 17 Click Save and Subrmit to save and submit.
