Download the file stroke dataset.csv to your R working directory on your computer. Then read the csv file into an R data frame called strokeDF. (As always in R, be sure to pay attention to case. Here the data frame name is lower case “stroke” and upper case “DF.”) Each row represents a person. For each person there’s an ID number, then ten characteristics (that should be self-explanatory). The last column indicates whether that indvidual had a stroke or not. Ultimately you will be asked to build and evaluate a Naive Bayes model to predict the occurrence of a stroke. There are no missing values in the data. The variable smoking_status includes values called “unknown.” For this exam, this is fine — just treat this as another value. (That is, you don’t have to do anything to deal with this.) How many people (rows) are in the data frame?
