Problem 8E

In an experiment to determine the effect of curing time on compressive strength of concrete blocks, two samples of 15 blocks each were prepared identically except for curing time. The blocks in one sample were cured for two days, while the blocks in the other were cured for six days. The compressive strengths of the blocks, in MPa, are as follows:

Can you conclude that the mean strength is greater for blocks cured for six days?
