Step-by-step explanation:
Just took the test and got 100%
Answer:
The best predicted IQ score is 103.
Step-by-step explanation:
We are given the following regression equation:
![y=100.2+0.00297x](https://tex.z-dn.net/?f=y%3D100.2%2B0.00297x)
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.
![y=100.2+0.00297(998)\\y=103.16406\\y\approx 103](https://tex.z-dn.net/?f=y%3D100.2%2B0.00297%28998%29%5C%5Cy%3D103.16406%5C%5Cy%5Capprox%20103)
Thus, the best predicted IQ score is 103.
Plant's height after 31 months:82 centimeters
<h3>How to find the height of the plant</h3>
The equation that can be used to find the height of the plant is given as
h = 52 centimeters + 1m
We have that the plant grows at 1 centimeter every month hence we have 1m in the equation.
Then the number of periods is m, Now we are to find the height in this period of time
h = 52 + 1*31
= 51 + 31
= 82
Hence the height after 31 months is given as 82 centimeters.
