2. Consider the below quotation from a recent New York Magazine article about a study of the effectiveness of masks in preventing virus transmission among school children: "It's also important to underline that just because the Georgia study did not find a statistically significant benefit doesn't mean that a larger, more statistically powerful study might not find one, said Hoeg, the epidemiologist. But since this study had 90,000 students, then the question becomes: If you need 500,000 or 1 million people to find a benefit, how marginal is that benefit?" Explain the last sentence in terms of what we have learned about statistical inference. (Hint: What is the relationship between sample size and standard error?)
