Question
N95 masks are made of a polypropylene material that goes through a process where it's melted
and extruded through small-diameter holes into hundreds of tiny fibers that are tangled
together. The meltblown fibers are randomly oriented with diameters ranging from 1-10
micrometers. A quality control engineers measures the diameters of the fibers and tests
H:µ=5 versus H:u# 5. If a Type I error is made, what conclusion will be drawn
regarding the average diameter of the fibers?
(A) The mean fiber diameter is equal to 5 micrometers.
(B) The mean fiber diameter is not equal to 5 micrometers.
If a Type II error is made in the preceding problem, , what conclusion will be drawn
regarding the average diameter of the fibers?
(A) The mean fiber diameter is equal to 5 micrometers.
(B) The mean fiber diameter is not equal to 5 micrometers
