A survey of 1379 parents and 1349 students in grades 6-12 regarding the importance of science and mathematics in the school curriculum found that 50% of students thought that understanding science and having strong math skills are essential for them to succeed in life after school, whereas 62% of the parents thought it was crucial for today's students to learn science and higher-level math. The two samples—parents and students—were selected independently of one another. (Use a statistical computer package to...
