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: Batch 1 2 3 4 5 After 6 days 1377 After 3 days 1335 1372 1364 1318 1354 1384 1350 1356 1328 Send data to Excel Part: 0 / 2 Part 1 of 2 (a) Construct a 99.8% confidence interval for the difference between the mean strengths of blocks cured three days and blocks cured six days. Let d represent the strength of blocks cured six days minus the strength of blocks cured three days. Use the TI-84 Plus calculator and round answers to one decimal place. A 99.8% confidence interval for the difference between the mean strengths of blocks cured three days and blocks cured six days is
