Please answer both parts thank you

6. A cancer study was conducted with female mice to determine the carcinogenic effect of food contaminated with 2 -acetylaminofluorene. The animals were sacrificed and examined after two years. The raw data are shown below: Determine the CSF using linear model. 7. Using the slope factor determined in Problem 6, determine the concentration of 2acetylaminofluorene that will give a risk of one tumor in 106 exposed female mice. 6.
