Multicollinearity may cause problems if the absolute value of the sample correlation coefficient for two of the independent variables exceeds what value? a. .7 b. 1 c. .5 d. .05

a. .7

Step-by-step explanation:

Multicollinearity means the two or more explanatory variables in a multiple regression model are highly linearly related to each other.

Multicollinearity is a problem because

Multicollinearity may cause problems if the absolute value of the sample correlation coefficient for two of the independent variables exceeds 0.7.

So, the correct option is a. .7 .

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
