Quizplus · Accepted Answer

Since the estimated 95 percent confidence interval for the slope coefficient does not include -5.75, it is still possible for the true slope coefficient to be equal to -5.75. It simply means that we cannot reject the null hypothesis that the true slope coefficient is equal to -5.75 based on the given confidence interval.
