Chapter 6, Problem 10(choose chapter or problem)
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 \(\mu\) greater than 1350 kPa.Asample of 100 blocks is produced and tested. Their mean compressive strength is 1356 kPa and their standard deviation is 70 kPa. A test is made of \(H_{0}: \mu \leq 1350 \text { versus } H_{1}: \mu>1350\)
a. Find the P-value.
b. Do you believe it is plausible that the blocks do not meet the specification, or are you convinced that they do? Explain your reasoning.
