The P-value is too small to have a conciustue answer. r. - b. The P-ualue is greater than 5% thus we are 1tier}:r certain that the averages are significantly different. r, I c. The P-value is greater than 5% we are not confident that the slope is not zero. r' - d. The P-value is smaller than 5% thus we are condent that the slope is not zero
