Question

Suppose you have estimated the parameters of a population regression function with 1 dependent and 4 independent variables (along with an intercept parameter) in Excel.

Suppose you have estimated the parameters of a population regression function with 1 dependent and 4 independent variables (along with an intercept parameter) in Excel. The table below summarizes your findings.

Coefficient Standard Error
Intercept 0.9 0.01
X Var 1 0.66 0.6
X Var 2 0.13 0.02
X Var 3 0.07 0.05
X Var 4 0.9 0.13

In the table above,X Var 1 represents the estimated parameter associated with the first independent variable. X Var 2 represents the estimated parameter fo the second independent variable. And so on.

Other than the intercept,:

Hint: There are two different ways to solve for this question. An approximate critical value (i.e., t value) of 2 would prove to be useful in both solution methods.

Group of answer choices

the parameters associated with the first and the third independent variables are statistically different from zero.

a. the parameters associated with the first and the fourth independent variables are statistically different from zero.

b. the parameters associated with none of the independent variables are statistically different from zero.

c. the parameters associated with the second and the third independent variables are statistically different from zero.

d. the parameters associated with the second and the fourth independent variables are statistically different from zero.

e. the parameters associated with all independent variables are statistically different from zero.
