A case-control study was conducted to find out whether meditation practice was negatively associated with blood pressure among adults. Investigators identified 100 adults with high blood pressure. The investigators recruited 400 people without normal or low blood pressure into the control group. All participants were given a questionnaire asking them whether they practiced meditation during the previous year. Among participants with high blood pressure, 25 reported that they practiced meditation during the previous year; a total of 125 control participants reported meditation. a. Create a 2x2 table for exposition (meditation) and health problem (high blood pressure). b. Calculate the odds ratio of having high blood pressure relative to those who meditated during the last year relative to those who did not. c. Interpret this odds ratio.
