An observational study of 2,391 people aged 65 or over was conducted. The researchers found that those who attended weekly religious services in person were 40% less likely to have high blood pressure than those who stayed home and watched the same weekly religious services via internet streaming. Which of the following is a valid conclusion? a. There could be lurking variables such as pre-existing health conditions.
b. Watching religious services via web streaming is boring and unhelpful.
c. Attending weekly religious services in person causes lower blood pressure.
d. We cannot make any conclusions because the study only included people aged 65 or over.

c. Attending weekly religious services in person causes lower blood pressure.

Step-by-step explanation:

From the study carried out about those who are 65 years and above but attending religious services in person rather than watching it online, it was able to show that, blood pressure is reduced.

This is because, they would walk before entering the religious service building as well as engage a little strenous exercise like dancing, singing etc which helps to put their body system in working state. On the other hand, those who watch it online became increasingly exposed to blood pressure due to their sedentary lifestyles of not moving around.
