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.

Based on this information, what is the prevalence rate of high blood pressure in diet soda drinkers?

Answer 1

The prevalence rate of high blood pressure in diet soda drinkers is 9%.

Step-by-step explanation:

The prevalence rate of high blood pressure in diet soda drinkers can be calculated by dividing the number of diet soda drinkers with high blood pressure by the total number of diet soda drinkers and multiplying by 100. In this case, there were 90 diet soda drinkers with high blood pressure out of 1,000 diet soda drinkers. So, the prevalence rate would be (90/1000) * 100 = 9%.
