Question

In multiple regression, the intercept must be tested to determine if it is significant.

True

False

The interpolation forecast represents a forecast using the actual data from which the regression equation was computed.

True

False

Answer 1

Answer #1

ANSWER:

Given that,

1) False, because we usually take the intercept as it without testing it for statistical significance.

2) True,because interpolation uses regression for predicting the values of Y at given values of X.

Answer both questions please true or false 16. The slope of the simple linear regression equation represents the average change in the value of the dependent variable per unit change in the independent variable (X). True/False 19. When using simple regression analysis, if there is a strong correlation between the independent and dependent variable, then we can conclude that an increase in the value of the independent variable causes an increase in the value of the dependent variable.
