State with brief reason why True or False

e. When we say that an estimated regression coefficient is statistically significant, we mean
that it is statistically different from 1.
f. To compute a critical t value, we need to know only the d.f.
g. By the overall significance of a multiple regression we mean the statistical significance of
any single variable included in the model.
h. Insofar as estimation and hypothesis testing are concerned, there is no difference between
simple regression and multiple regression.

Expert Solution

Step 1: Introduction

When we say an estimated regression coefficient is statistically significant, it means that it is statistically different from zero, not necessarily from $1$ .
