Question

Interpret the following non-significant Unstandardized coefficient: b = -3.09

Answer #1

It is given that the unstandarddized coefficient b = -3.09 is non-significant.

Suppose it is nonsignificant with the value zero.

That means from the sample information we cannot conclude that the population coefficient is different from zero. The confidence interval of the corresponding population coefficient based on b include zero.

From this non-significance we also conclude that the independent variable corresponding to this coefficient is not usefull for estimating values of the dependent variable.

Interpret the following non-significant Unstandardized
coefficient: b = -3.09

1) Write the
regression equation.
2) Explain the value
of unstandardized B coefficient.
3) Explain the value
of standardized B coefficient.
4) What null
hypothesis is being tested?

thank you for yor help.

Which of the following statements are correct?
I. The fact that a coefficient is statistically significant
necessarily means it is economically significant as well.
II. Multicollinearity is a violation of No perfect collinearity
assumption. (MLR.3)
a. Only I
b. Only II
c. Both I and II
d. Neither I nor II
