A company produces ball bearings for industrial applications. The bearings a manufactured to be precisely 2.75 mm in diameter. Every 30 minutes, a quality control officer takes a random sample of ball bearings from the assembly line and measures each to ensure that the average diameter of the sample is not significantly different than 2.75 mm. Determine the null and alternative hypotheses for the above hypothesis test. Ho 2.75, H < 2.75 Ho2.75, H = 2.75 : : < 2.75, H1: > 2.75 Ho= 2.75, H 2.75
