Create a binary variable, named died_in_hospital, that takes the value 1 when the date of death is the same as the date of hospital discharge and takes the value 0 otherwise. Technically, a patient can be discharged from the hospital on a particular day and die at another location on the same day. Ignore that scenario and consider such instances as died in hospital.Calculate the proportion of patients who died in hospital in patients who had DNR status on day 1 and in patients who did not have DNR status on day 1. Estimate the odds ratio of in-hospital death between patients with and without DNR status on day 1. Is there sufficient evidence to conclude that the odds of in-hospital death differ between patients with and without DNR status on day 1
