The data give the survival status of passengers, together with their names, age, sex and passenger class. Variable Description Recorded name of passenger Name PClass Age Sex Survived Passenger class: 1st. 2nd or 3rd Age in years male or female 1 = Yes, 0 No (a) Plot a graph to compare two qualitative variables: the survival status of passengers (us- ing the variable Survived) and passenger gender (using the variable Sex). You can use any graph you like. (b) Create a two-way frequency table using the variables Survived and Sex. (c) Assess the evidence that survival is independent of passenger gender (using the vari- ables Survived and Sex). disaster.txt ⑦
