In a multiple regression model, there are 10 independent variables included in the model. Therefore the sample size should be at least 10.
  Indicate whether the statement is true or false

Q. 2

Consider a multiple regression model with three independent variables. If the y-intercept is negative, then at least two of the partial regression slope coefficients will also be negative.
  Indicate whether the statement is true or false

Q. 3

In a multiple regression model, the partial regression slope coefficients measure the average change in the dependent variable for a one-unit change in the dependent variable of interest, with all other independent variables held constant.
  Indicate whether the statement is true or false

Q. 4

The multiple coefficient of determination measures the proportion or percentage of variation in the dependent variable that is explained by the independent variables included in the model.
  Indicate whether the statement is true or false

Q. 5

In a multiple regression model, there is only one dependent variable and two or more independent variables.
  Indicate whether the statement is true or false

Q. 6

The adjusted coefficient of determination is adjusted for the number of independent variables in the model by using sum of squares rather mean squares.
  Indicate whether the statement is true or false

Q. 7

In a multiple regression model involving 5 independent variables, if the sum of the squared residuals is 847 and the data set contains 40 points, then, the value of the standard error of the estimate is 24.911.
  Indicate whether the statement is true or false
