A set of data points has a line of best fit of ý = 2.5x - 1.5. What is the residual for the point (2,5)?
A. 3.5
B. -1.5
C. 5
D. 1.5

D. 1.5

Step-by-step explanation:

A residual is generally a quantity left over at the end of a process. In this case, I am going to say it is the distance from the given line.

f(x) = -1.5 + 2.5x

f(2) = -1.5 + 2.5(2)

f(2) = -1.5 + 5

f(2) = 3.5

distance from (2,5) to (2,3.5):

d = sqrt((delta x)^2 + (delta y)^2)

d = sqrt((2 - 2)^2 + (5 - 3.5)^2)

d = sqrt((0)^2 + (1.5)^2)

d = sqrt((1.5)^2)

d = 1.5 ANSWER

C.) 1.5 for courseapx

Step-by-step explanation:

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
