a. Propose a straight-line model relating math score (y) to percentage (x) of students below the poverty level.
b. Use the method of least squares to fit the model to the data in the FCAT file.
c. Graph the least squares line on a scatterplot of the data. Is there visual evidence of a relationship between the two variables? Is the relationship positive or negative?
d. Interpret the estimates of the y intercept and slope in the words of the problem.
e. Now consider a model relating reading score (y) to percentage (x) of students below the poverty level. Repeat parts a-d for this model.
