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:
x

)
Explanation:
The equation of a parabola in vertex form is.

)
2

Where (
h
,
k
) are the coordinates of the vertex and a is a multiplier
f
(

−
9 is in this form
with (
h
,
k
)
=
(
5
,
−
9
)
⇒
vertex =
(
5
,
−
9
)
the axis of symmetry passes through the vertex is vertical with equation
x
=
5
← axis of symmetry graph{(y-x^2+10x-16)(y-1000x+5000)=0 [-20, 20, -10, 10]}
