Use the data consisting of IQ score and brain volume

ArbitrLikvidat [17]

Answer:

The best predicted IQ score is 103.

Step-by-step explanation:

We are given the following regression equation:

$y=100.2+0.00297x$

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.

$y=100.2+0.00297(998)\\y=103.16406\\y\approx 103$

Thus, the best predicted IQ score is 103.

How do u find cost to store and markup

maria [59]

To find a markup price, you multiply by the percentage marked up, and then add that to the original cost to get your new cost.

Example: a pair of jeans that cost $64 is marked up 35%.
multiply 64 and 0.35 = 22.4
add 22.4 to 64 =86.4
the markup price of the jeans is $86.40

hope this makes sense!
