Strength of concrete: The compressive strength, in kilopascals, was measured for concrete blocks from five different batches of concrete, both three and six after pouring. The data are as follows. Can you conclude that the mean strength after three days is less than the mean strength after six days? Let U1 represent the mean strength after three days and ud=u1-u2, Use the a=0.01 level and the critical value method with the table. 1. State the appropriate null and alternate hypotheses....

The canoe team from the previous problem wishes to prove that their compressive strength of 900 psi is indeed greater than the required 860 psi. To do so, they write out a number of hypotheses: A: Our concrete is stronger than required, μ > 860 B: Our compressive strength is great, μ = 900 C: Our concrete meets the requirement, μ = 860 D: Typical concrete is weaker than ours, μ < 900 Of these four potential hypotheses which should...
