Explanation / Answer
Question 1:
Multiple linear regression is the linear regression of 1 dependent variable with more than one independent variables.
Therefore b) is the correct answer here.
Question 2:
The coefficient of the independent variable in the regression equation gives both the magnitude as well as the direction of the relationship between the dependent variable y and the independent variable x. Therefore c) is the correct answer here.
Question 3:
If the slope coefficient of a independent variable is 0, the there is no relationship between the dependent variable y and the independent variable x. Therefore a) is the correct answer here.
Question 4:
Here as the line is going upwards, the slope is positive. Therefore c) is the correct answer here.
Question 5:
As the line is intersecting y at 40, therefore y intercept here is 40. Therefore d) is the correct answer here.
