A production grinder at work uses a very expensive, diamond-coated wheel to grind ceramic parts flat. The print spec for flatness is "flat within 0.003"." If the actual part flatness goes outside of this value, then the wheel is sent out to be re-surfaced flat again. Which is also a very expensive process. 1. Describe and define the alpha and beta risks associated with the decision to re-surface the wheel. (2 pts.) 2. You check 15 parts as shown below. At 95% confidence, should the wheel be re-surfaced? Or continue to run it? Use an appropriate t-test. Clearly show all 8 steps. (3 pts.) Hint - this is not a two-tailed test. 0.0029 0.0026 0.0029 0.0034 0.0027 0.0033 0.0025 0.0028 0.0027 0.0028 0.0029 0.0029 0.0027 0.0032 0.0028
