At a certain manufacturing plant, a machine produced ball bearings that should have a diameter of 0.50 mm. If the machine produces ball bearings that are either too small or too large, the ball bearings must be scrapped. Every hour, a quality control manager takes a random sample of 30 ball bearings to test to see if the process is "out of control" (i. e. to test to see if the average diameter differs from 0.50 mm).
a. Which form of the hypotheses should be used to test the manager's claim?
H0: -
mu is greater than or equal to 0.50
mu is less than 0.50
mu is less than or equal to 0.50
mu is equal to 0.50
mu is not equal to 0.50
Ha:
- -mu is greater than or equal to 0.50
mu is greater than 0.50
mu is less than or equal to 0.50
mu is equal to 0.50
mu is not equal to 0.50Item 2
