A factory that manufactures bolts is performing a quality control experiment.
Each object should have a length of no more than 20 centimeters. The factory
believes that the length of the bolts exceeds this value and measures the length
of 59 bolts. The sample mean]bolt length was 20.05 centimeters. The
population standard deviation is known to be o = 0.16 centimeters.
What is the test statistic z? Ex: 1.23=
What is the p-value? Ex. 0.123
Does sufficient evidence exist that the length of bolts is actually greater than
