The compressive strengths of four concrete mixes with different water / cement ratios are shown in the table below. Using a linear regression analysis, calculate the slope of the best fit line (a1) on a plot of compressive strength vs. water cement ratio. Water / cement ratio Compressive strength (N/mm2) 0.40 51.7 0.45 45.7 0.50 43.1 0.55 36 NB. Write answers to 3 significant figures
