  From the following Minitab regression analysis, what can you conclude for the hypothesis test of H₀: versus H_a: using ?
 
 

  a.The null hypothesis would be rejected and the conclusion would be that the x variable is necessary for the regression model to predict y.
  b.The null hypothesis would not be rejected and the conclusion would be that the slope of the regression line is equal to zero.
  c.The null hypothesis would be rejected and the conclusion would be that the y-intercept of the regression model is equal to zero.
  d.The null hypothesis would not be rejected and the conclusion would be that the x variable is of no use in the regression model to predict y.

Question 2

  Which of the following is not a property of r_yx?
 

  a.The square of the correlation coefficient is the value for the coefficient of determination that results from fitting the simple linear regression model.
  b.
  c.The value of r_yx depends on the units in which x and y are measured.
  d.The strength of the linear relationship is determined by the closeness of the points to a straight line.
