Question: Consider the SAT and spending data: Is there a correlation between the average annual salary of teachers in public elementary schools and secondary schools and the average math SAT scores? What does the scatterplot look like? Is the correlation significant?

for every increase of 1,000 dollars in teacher pay, what is the corresponding

change in the math SAT score? If a state spends 40,000 dollars per year, on average, per teacher, what math SAT score should they expect? Should teachers receive more or less pay to improve math SAT scores? explain why this relationship may exist.

Give an appropriate interpretation of the r² value.
