Answer:
The correlation between the Math SAT and the Verbal SAT computed from the data on all the individuals who took the tests would be less than 0.97.
Step-by-step explanation:
Averaging data into blocks (in this scenario, by State) tends to a reduction in variation and an increase in correlation between the studied variables. Therefore, when applying regression to the original individual data, a reduced correlation would be expected:
Therefore, the correlation between the Math SAT and the Verbal SAT computed from the data on all the individuals who took the tests would be less than 0.97.

Answer: Third option is correct
Step-by-step explanation: The y-intercepts match the constants (b in y=mx+b format) The y-values shaded above the line y≥2x+4 are correct. The y-values shaded in the region below the y≤2x -2 are also correct.
