Is there evidence to support the claim that the mean grind- ing force increases with the vibration level? b. Find a 95% confidence interval for the difference in the mean grinding force for the two vibration levels. c. Is the value zero contained in the 95% confidence interval? Explain the connection with the conclusion you reached in part (a). d. Do normal probability plots of grinding force indicate any violations of the assumptions for the tests and confidence interval that you performed?

5.6.5 WP An article in Knee Surgery Sports Traumatology, Arthroscopy ["Effect of Provider Volume on Resource Utilization for Surgical Procedures" (2005, Vol. 13, pp. 273–279)] showed a mean time of 129 minutes and a standard deviation of 14 min- utes for ACL reconstruction surgery for high-volume hospitals (with more than 300 such surgeries per year). If a high-volume hospital needs to schedule 10 surgeries, what are the mean and variance of the total time to complete these surgeries? Assume that the times of the surgeries are independent and normally distributed.
The article "Application of Analysis of Variance to Wet Clutch Engagement" (M. Mansouri, M. Khonsari, et al., Proceedings of the Institution of Mechanical Engineers, 2002:117-125) presents the following fitted model for predicting clutch engagement time in seconds (y) from engagement starting speed in m/s (x1), maximum drive torque in N · m (x2), system inertia in kg · m² (x3), and applied force rate in kN/s (x4): y = -0.83 + 0.017.x, + 0.0895x, + 42.77.xz + 0.027x, – 0.0043x,x, The sum of squares for regression was SSR = 1.08613 and the sum of squares for error was SSE = 0.036310. There were 44 degrees of freedom for error. Predict the clutch engagement time when the starting speed is 20 m/s, the maximum drive torque is 17 N·m, the system inertia is 0.006 kg · m², and the applied force rate is 10 kN/s. b. Is it possible to predict the change in engagement time associated with an increase of 2 m/s in starting speed? If so, find the predicted change. If not, explain why not. Is it…
5.47 Ambulance response time. Ambulance response time is measured as the time (in minutes) between the initial call to emergency medical services (EMS) and when the patient is reached by ambulance. Geographical Analysis (Vol. 41, 2009) investigated the characteristics of ambu- lance response time for EMS calls in Edmonton, Alberta. For a particular EMS station (call it Station A), ambulance response time is known to be normally distributed with u = 7.5 minutes and o = 2.5 minutes. a. Regulations require that 90% of all emergency calls should be reached in 9 minutes or less. Are the regula- tions met at EMS Station A? Explain. b. A randomly selected EMS call in Edmonton has an am- bulance response time of 2 minutes. Is it likely that this call was serviced by Station A? Explain.
Four different formulations of an industrial glue are being tested. Each of the different formulations were randomly applied to joint parts of five test specimen and the tensile strength of the glue when it is applied to each test specimen is recorded. However, the tensile strength is also related to the application thickness. The data on the strength (in lbs) and thickness (in 0.01 inches) are shown in the following table. Assuming all assumptions for ANOVA/ANACOVA to be valid are satisfied, perform the NECESSARY tests of hypotheses to determine if there are differences on the different formulations of an industrial glue at 5% level of significance.
