Question 6(25%) : You have been running laboratory trials on mice to validate a new treatment for the deadly and antibiotic-resistant Sietus bacterial infection. You are attempting to stop the infection by introducing artificially engineered bacteriophages into the lab animal's blood that will seek out and destroy the Sietus microorganism. By manipulating the base plate protein width of the bacteriophages you have improved their potency and animal longevity. After determining the base plate width and infecting the animal with Sietus, you track the animal's survival. The data is on the code box, where the first row is plate width (nanometers) the second row is animal survival (days post infection) and each column is an observation of a different animal. a. (5\%) Fit a regression line to the data and comment on the quality of the model. b. (10\%) Fit a cubic polynomial to the data and report the value of each coefficient and the P2. c. (5\%) Generate a plot containing the data, the linear model predictions, and the cubic model predictions. e. (5\%) Based on previous findings, if the animal survives for 40 days, it will very likely clear the infection and never succumb to the Sietus. According to the cubic function model, what is the minimum bacteriophage base width needed to achieve a 40 day survival? Your answer for the base width can be within 0.01 days, that is 400.01. Hint: One approach is to systematically test values with a loop until one is found that satisfies the requested tolerance of 0.01 days
