To create a deterministic model, we start with a probabilistic model that approximates the relationship we want to model.
  Indicate whether the statement is true or false

Q. 2

The first-order linear model is sometimes called the simple linear regression model.
  Indicate whether the statement is true or false

Q. 3

Statisticians have shown that sample y-intercept b0 and sample slope coefficient b1 are unbiased estimators of the population regression parameters 0 and 1, respectively.
  Indicate whether the statement is true or false

Q. 4

The residuals are observations of the error variable . Consequently, the minimized sum of squared deviations is called the sum of squares for error, denoted SSE.
  Indicate whether the statement is true or false

Q. 5

The residual ri is defined as the difference between the actual value yi and the estimated value y1.
  Indicate whether the statement is true or false

Q. 6

The method of least squares requires that the sum of the squared deviations between actual y values in the scatter diagram and y values predicted by the regression line be minimized.
  Indicate whether the statement is true or false

Q. 7

The vertical spread of the data points about the regression line is measured by the y-intercept.
  Indicate whether the statement is true or false
