A new concrete mix is being designed to provide adequate compressive strength for concrete blocks. The specification fora particular application calls for the blocks to have a mean compressive strength greater than 1350 kPa. A sample 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 Ho: u < 1350 against H1: µ > 1350. Is the following statement True or False? If the p-value calculated is not a small probability, then it can be concluded that the mean compressive strength is greater than 1350 kPa and that the blocks meet the specification. O True False

Question
Transcribed Image Text:A new concrete mix is being designed to provide adequate compressive strength
for concrete blocks. The specification fora particular application calls for the blocks
to have a mean compressive strength greater than 1350 kPa. A sample 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 Ho: u < 1350 against
H1: µ > 1350. Is the following statement True or False? If the p-value calculated is
not a small probability, then it can be concluded that the mean compressive
strength is greater than 1350 kPa and that the blocks meet the specification.
