A certain medication that is frequently prescribed to lower a patient's cholesterol level is generally effective. █ ██████ █████ ██ █████ ████████ ███████ ██████ ██ ███ ██████████ ████████ ████ ███ ███████████ █████ ██ ███████ ██████ ███ ██████████ ██ █████████ ██ ██ ██ ███████ ██████ ████ ███ ███████ ███ ████ ████████ ███ ██████
Why would the cholesterol of someone taking the medication be typically higher than the average cholesterol of someone in that person’s age group even though the medication is effective in lowering cholesterol?
The correct answer should tell us about a difference between people who take the medication and people who don’t that might explain why people who take the medication have higher average cholesterol despite the medication’s effectiveness. For example, maybe people who take the medication start off with above average cholesterol, which could be why the take the medication in the first place. Or maybe people who take the medication engage in cholesterol-increasing activities that the average person does not.
