6. 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 ,ul represent the mean strength after three days and pad 2 #1 #2. Use the a = 0.05 level. Block 1 2 3 4 5 After 3 days 1354 1311 1338 1330 1307 After 6 days 1341 1371 1351 1320 1327 a. State the null and alternate hypotheses. b. Compute the test statistic. c. State a conclusion
