You are given a sample of data from the U.S. Census at School, an international classroom project that engages students in grades 4-12 in statistical problem solving. Students complete a brief online survey, analyze their class census results, and compare their class with random samples of students in the United States and other countries.

We are interested in studying comparing all participating students in grades 4-12 from the states of California, Hawaii, and Pennsylvania.

Your random sample includes 562 randomly selected responses stored on the Census at School website. Only responses from students living in California, Hawaii, and Pennsylvania are included. See the attached key to understand the subset of questions we have included responses for.
