When a manufacturing process is operating properly, the mean length of a certain partis known to be 6.175 inches, and lengths are normally distributed. The standarddeviation of this length is 0.0080 inches. If a sample consisting of 6 items taken fromcurrent production has a mean length of 6.168 inches, is there evidence at the 5%level of significance that some adjustment of the process is required?Given: mu, o, n, x, 5% level of significanceApproach: compare z-values (test statistic z vs critical z1=-1.96); p-values (O (-z1) and1- 0 (z1) vs 5%); x values (critical x value vs š)

In order to test the claim that the process needs some adjustments, determine whether the mean…
