Question

he Y-intercept of a regression line is −14, and the slope is 3.5. Which of the following is not correct? Multiple Choice

When Y increases by one, X increases by 3.5.

When X increases by one, Y increases by 3.5.

The regression line crosses the Y-axis at −14.

X and Y are positively related.

None of the options are correct.

Answer 1

Answer:

As the incline is certain i.e., X and Y are decidedly related (+) for slant = 3.5

Thus when X increments by one then Y increments by 3.5

for capture = - 14 then that demonstrated that at x = 0 ; y = - 14 and

consequently relapse line crosses the Y-hub i.e., axis at - 14.

So

Option A is incorrect

At the point when Y increments by one, X increments by 3.5
