A manufacturer of industrial bolts for riding mowers requires that a particular type of bolt be 12.0 mm. in diameter. Periodically, the company draws an SRS of 30 bolts from recent batches and measures them to determine whether the manufacturing process is producing the desired diameter. The null hypothesis is H0: μ = 12.0 . The alternative hypothesis is HA: μ ≠ 12.0 .

In the most recent sample, the mean diameter was 12.03 mm. and the sample standard deviation was 0.08 mm.
