• B)because the ESTIMATED values of the intercept and slope parameters are not,in general,equal to the true values of the intercept and slope parameters.
• C)because the computed t-ratios are random variables and may be too large to provide evidence that b is not equal to zero.
• D)in order to determine whether or not the parameter estimates are far enough away from zero to conclude that the true parameter values are not equal to zero.
