Question
The resistivity of the produced kits is also tested. The mean resistivity is 230 Ohm. The production manager
suspects that the production line is producing too many out-of-tolerance components and should be stopped
and serviced. The quality assurance department in the company decided to make a study by taking a random
sample of 37 kits and testing their resistivity. It is found that the mean resistivity of the sample kits is 225.6
Ohms, with a standard deviation of ?? = 3.5 Ohms. Using a level of significance of 0.05 and 0.1:
G) determine whether there is enough evidence to support that the production manager’s claim is
reasonable.
H) What can you conclude from the conducted hypothesis test?
