Questions 1-5 are related to the CVD-Data and Question 6 is related to the diastolic blood pressure (DBP) Data.Question 3 [35 marks]: Using appropriate statistical method(s) investigate whether patients who had a history of being treated with Drug-X on a regular basis have significantly different systolic blood pressure (SBP), diastolic blood pressure (DBP) and cholesterol level (CHL) compared to patients who were not treated with Drug-X.Please fill up the following table from the above analysis results [Note: 3 marks will be allocated for filling up this table with relevant data].Question 1 [7 marks]: Consider that an investigator aims to assess whether followed-up mortality (DEATH) was related to body mass index (BMI, a categorical variable) in the study sample. Evaluate the investigator’s aim by presenting the related data on an appropriate graph (Hint: no additional summary statistics or significance test required).Question 2 [10 marks]: Using an appropriate graphical presentation discuss whether diastolic blood pressure (DBP) is related to body mass index (BMI, a categorical variable) in the study sample (Hint: no additional summary statistics or significance test is required). Based on the findings can you make an inference on the study population? Justify your answer.Question 4 [16 marks]: Using an appropriate statistical method evaluate the significance of difference of SBP across the following categories of BMI: BMI
