Answer:

the third option

Step-by-step explanation:

a1 = 3

a2 = -9

as a geometric sequence every sequence item is created by multiplying a constant factor with the previous item.

what do I need to multiply 3 with to get -9 ? right, -3.

so, the first 2 options are out, because they multiply with -12.

and we can accept only n>=1, because there is no a0. it starts with a1.

ah only the third option is right.

Answer:

the residual is 0.2032

Step-by-step explanation:

The regression line has been given as:

Y^ = 0.00753X-0.06759

The paired observation for X is (31, 0.369)

The value of X is the empathy score under subject 15 = 31

The value of the brain activity under subject 15 is 0.369

So we have y^ = 0.00753(31) - 0.06759

= 0.1658

Then the residual = y - y^

= 0.369 - 0.1658

= 0.2032

Therefore the residual is 0.2032

Please check the attachment for the table, it will aid you in understanding the solution
