Question

Researchers were interested in the relationship between the consumption of diet soda and blood pressure. They interviewed 2,000 people—1,000 people who drank 1 or more diet sodas per day and 1,000 people who did not drink diet soda. Among those that drank diet soda, 90 people had high blood pressure; in the non-soda drinking group, there were 10 cases of high blood pressure.

Using the information from above, which of the following 2x2 tables is correct?

Answer 1

A 2x2 table correctly representing the relationship between diet soda consumption and high blood pressure shows that among diet soda drinkers, 90 out of 1000 have high blood pressure, and among non-soda drinkers, 10 out of 1000 have high blood pressure.

Step-by-step explanation:

The scenario provided involves researchers investigating the relationship between consumption of diet soda and blood pressure. The study involves 2,000 participants, with 1,000 people who consume one or more diet sodas per day and another 1,000 who do not. The number of people with high blood pressure in the diet soda group is 90, whereas in the non-soda group, it is 10. To represent this data clearly, the correct 2x2 table would have the group status (diet soda vs. non-diet soda) as one axis and the blood pressure status (high vs. normal) as the other. Each cell of the table should then reflect the corresponding number of people in each category.

Here is the correct 2x2 table based on the given information:

High Blood Pressure Normal Blood Pressure

Diet Soda Drinkers

90 910 Non-Diet Soda Drinkers 10 990

This table should accurately reflect the details provided in the question regarding the relationship between diet soda consumption and blood pressure within the study sample.
