A machine shop manufactures ball bearings with a diameter of 15 mm. However, the diameter of the ball bearings varies slightly. To check that the manufacturing process is operating correctly, a random sample of 25 ball bearings is selected. The mean diameter is 15.018 mm with a standard deviation of 0.055 mm. You are to test if the data provide convincing evidence that the true mean diameter of all ball bearings is greater than 15 mm. Use a significance level of a 0.10. Assume that the distribution of diameters is approximately normal. Find the test statistic and the critical value. Assume all conditions for the test have been met. The test statistic is t-i The critical value is i Enter your answer using two decimal places. Enter your answer using three decimal places.
