Compute the test statistic

Strength 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 is greater than the mean strength after six days? Let u, represent the mean strength after three days and J = ] -H2. Use the a=0.01 level and the P-value method with the table. EO Block 2 3 4 5 After 3 days 1389 1380 1302 1377 1336 After 6 days 1314 1321 1318 1386 1356 Send data to Excel Part 1 of 5 V (a) State the appropriate null and alternate hypotheses. Ho: H = 0 H: H > O This is a right-tailed test
