The Pennsylvania Department of Education is interested in the relationship between per-student spending and
average SAT Math scores. A scatter plot of the data suggests average SAT Math scores tend to increase as
per-student spending in a school district increases. The Department of Education is interested in whether this
increase is significant. Assuming conditions for inference are satisfied, the p-value for the linear regression
t-test is approximately
A. 0.0001
