Suppose A new study published in a prestigious medical journal claims that drinking coffee every day can extend lifespan by reducing the risk of certain chronic diseases. The research, conducted over a span of 10 years, analyzed data from thousands of participants and found a strong correlation between coffee consumption and longevity. However, some experts are skeptical of the findings, citing potential confounding variables that may have influenced the results. As the debate over the health benefits of coffee continues, coffee sales have surged in response to the study's positive publicity.
Can we infer that "All medical journals agree that drinking coffee extends lifespan."? Yes, no, or maybe?
