You perform a similar experiment to problem 2, but this time you measure using qPCR the expression of a certain gene of interest where a certain drug was added at various increasing concentrations (drug units in mmol/l). The data are in the le \"gene_regression.csv\". Perform an appropriate linear regression. What is the best tting line equation? Check the linear model assumptions using diagnostic plots. Analyse the t of the model, and F-statistic and p-value and report your conclusions
