Median Annual Score
The scatterplot shows the median annual score obtained by students of different schools in the third grade and obtained by the same students when promoted in the seventh grade. The correlation is 0.794. The regression equation is above the graph.
a. Find a rough estimate (by using the scatterplot) of median score for a seventh-grade student who had a median score of 8 in third grade.
b. Use the regression equation above the graph to get a more precise estimate of the median score in the seventh grade for a student who had a median score of about 8 in the third grade.
