The table below shows the inside diameter of a bored hole, on a mild steel castings from two well-known brands of CNC Lathe. Brand A 25.502 25.501 25.502 25.504 25.502 25.505 25.504 25.503 25.503 25.501 25.502 25.503. Brand B 25.506 25.501 25.500 25.502 25.501 25.503 25.506 25.502 25.505 25.504 Brand B is currently available for 25,000 euro less than Brand A, so if there is no difference between them we will purchase the cheaper Brand B. What would you conclude at the 5% level of significance? Q 5(b) Construct a 95% confidence interval for the difference in the two machines?
