Students will be presented with a crime scene investigation/murder mystery challenge where they need to create a linear model and use it to determine a y-value (time of death) of a particular x-value (hypoxanthine concentration in a posthumous eye). Students will be encouraged to develop hypotheses for what happened to the dead victim--if the individual was murdered or not. Data for hours after death and hypoxanthine concentration will be provided. They will be asked to calculate the time of death with both mean confidence intervals (CIs) and individual CIs for the data around the slope. Lastly, students will interpret results to then evaluate their hypotheses and determine whether they have enough evidence to conclude that a murder took place or not.
