A new concrete mix is being designed to provide adequate compressive strength for concrete blocks. The specification for a particular application calls for the blocks to have a mean compressive strength μ greater than 1350 kPa. A sample of 100 blocks is produced and tested. Their mean compressive strength is 1,357 kPa and their standard deviation is 72.0 kPa. A test is made of H0 : µ ≤ 1350 versus H1 : µ > 1350. Find the P-value. (Round the final answer to four decimal places.)
