From the given output, we can see that the coefficient for the independent variable (X) is -0.325 and its standard error is 0.107. The test statistic for testing whether the regression slope coefficient is equal to zero can be calculated as t = (coefficient - hypothesized value)/standard error. Here, the hypothesized value is zero. Thus, t = (-0.325 - 0)/0.107 = -3.04 (rounded to two decimal places). Therefore, the best choice is A, which is approximately t = 3.04.
