A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than 10
centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of 84

centimeters. The population standard deviation is known to be
=
0.12
centimeters.
What is the test statistic z
?
What is the p
-value?

=
0.05
?
