janice wants to collect data on the prevalence of each fingerprint pattern among the students at her high school to see how close they fall to the national average. Which of the following scenarios should Janice follow to obtain the most reliable data, but without requiring any extra work.

People just need to follow instructions. They need to stop going out unless absolutely necessary, and if they do.. they need to wear a mask. Although I do agree that people are making it seem much worse than it is. If we want things to return to normal we need to follow directions. My family has bought enough masks for our direct family and some hand sanitizer (all reasonable amounts, unlike some people)
