rength of concrete: The compressive strength, in kilopascals, was measured for concrete blocks from five different batches of concrete, both three and six days after pouring. The data are as follows. Can you conclude that the mean strength after three days differs from the mean strength after six days? Let H, represent the mean strength after three days and P =H, -P. Use the a=0.01 level and the P-value method with the TI-84 Plus calculator.
