Please see the atttached and help me with the correct answer?

A factory that manufactures bolts is performing a quality control experiment.
Each object should have a length of no more than 16 centimeters. The factory
believes that the length of the bolts exceeds this value and measures the length
of 85 bolts. The sample mean bolt length was 16.03 centimeters. The
population standard deviation is known to be o = 0.15 centimeters.
What is the test statistic z?
What is the p-value?
Does sufficient evidence exist that the length of bolts is actually greater than
the mean value at a significance level of a = 0.05?
