Answer:

The best predicted IQ score is 103.

Step-by-step explanation:

We are given the following regression equation:

[tex]y=100.2+0.00297x[/tex]

where y is the predicted IQ score and x is the brain volume.

y is the dependent variable and x is the independent variable.

Significance level = 0.05

We have to find the best predicted IQ score with a brain volume of 998 cubic cm.

We put x = 998 in the equation.

[tex]y=100.2+0.00297(998)\\y=103.16406\\y\approx 103[/tex]

Thus, the best predicted IQ score is 103.
