Question 1 : An experiment was conducted to determine the effects oftwo different drugs on reducing the growth of tumor size for patients with stomach cancer in Saskatelierwan, For each patient, and after 6 months of taking the drug, funor size reduction was measured, at a given claire value, as a percentage of the original size before taking the drug. All recordings are Done Amount of Drug (in nig) "A" to Tuner Size Reduction (Al and Dave Amount of Drug (in ma) "I" () 3 Tumor Size Reduction (hil 1. [14 points) Find the best fitting line (between a and y) for each drug and plot it. Plot both lines at one.graph 2. (3 points) Find the point of intersection of both lines in part 1. A. (4 points) Find the relative potency of Drug "B" relative to Drug "A at a = 2 Jung and a = 6.3mg Hint : Itdative potency refers to "the ratio of the predicted values of Drug "B" relative to Drug "A" at a given dose (r) value", that is at x - 23mg Solution .
