Question

question 7 (1 point)(05.07 mc)an observational study determined that there is a strong correlation between sitting close to the television and poor eyesight. can it be determined that sitting too close to the television causes poor eyesight? explain.a causation cannot be proven because everyone watches television.b causation can be proven because it is well known that sitting close to the television causes poor eyesight.c causation can be proven because an experiment was used to prove this hypothesis.d causation cannot be proven because poor eyesight can occur for other reasons, such as genetics.question 8 (1 point)

Explanation:

Correlation does not equal causation. An observational study only shows a relationship, not that one variable directly causes the other. Poor eyesight can stem from other factors like genetics, so we cannot confirm sitting close to a TV is the cause. Option a is incorrect because universal TV watching is irrelevant. Option b is wrong as common belief does not equal proven causation. Option c is incorrect because an observational study, not an experiment, was done.

Answer:

d. Causation cannot be proven because poor eyesight can occur for other reasons, such as genetics.
