Problem 2 You perform an experiment measuring the response on cellular calcium concentration in cell cultures where a certain drug was added at various increasing concentrations (units in mmol/l). The data are in the le \"calcium_regression2.csv\". What experimental design is this? Plot the data. What kind of plot is this? Show condence intervals. Perform an appropriate linear regression. What is the best tting line equation? Show this on the plot, including 95% condence bands. Check the linear model assumptions using diagnostic plots. Predict What the calcium level would be for a drug level of 0.55 mmol/l. Specify the null model. Analyse the t of the model, and Fstatistic and pvalue and report your conclusions. #
