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.
Identify the treatment (specify levels), experimental units, concomitant variable, and response variable.
An army depot that overhauls ground mobile radar systems is interested in improving its processes. One problem involves troubleshooting a particular component that has a high failure rate after it has been repaired and reinstalled in the system. The shop floor supervisor believes that having standard work procedures in place will reduce the time required for troubleshooting this component. Time (in minutes) required troubleshooting this component without and with the standard work procedure is recorded for a sample of 19 employees. Assuming that we define our differences as Time without standard work procedure - Time with standard work procedure, and the p-value associated with the test statistic is less than 0.0001. At alpha = 0.05,
I. we reject the null hypothesis
II. we fail to reject the null hypothesis
III. we can conclude that having standard work procedures in place reduces troubleshooting time for this component

- Suppose that Rob is a quality control specialist at a toothpaste factory. Part of his job is to verify that the filling machines are dispensing the proper amount of toothpaste into each tube. It is his first day working on a new machine that fills travel size toothpaste tubes. The machine is calibrated with an average fill rate of 0.75 ounces of toothpaste per tube. Rob randomly samples 16 of the 1000 travel size tubes of toothpaste that the machine produces that day. The weight, in ounces, of Rob's sample data is presented in the stem-and-leaf plot below. The stems are tenths of an ounce and the leaves are hundredths of an ounce. 5 9 6 6 7 7 8 3 4 8 5 2 3 5 6 8 0 0 0 2 6 6 6 Rob does not know the population standard deviation, so he decides to perform a one-sample t-test to determine if the machine is filling the tubes with the proper amount of toothpaste.

Some variation of course, is to be expected. But too much presents a production issue. Your job is to find out if this process is stable enough to continue. Samples are taken for 20 days. The number of boxes checked each day is 100. The 20 samples measured reveal the following proportions found to have defective weights: Sample Number Of Defectives Proportion Defective 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 6 0.06 0 0.00 4 0.04 10 0.10 6 0.06 4 0.04 12 0.12 10 0.10 8 0.08 10 0.10 12 0.12 10 0.10 14 0.14 8 0.08 6 0.06 16 0.16 12 0.12 14 0.14 20 0.20 18 0.18 Complete the following: Calculate the centerline (CL), upper control limit (UCL), and the lower control limit (LCL) for a P- Chart.

- Foot ulcers are a common problem for people with diabetes. Higher skin temperatures on the foot indicate an increased risk of ulcers. The article "An Intelligent Insole for Diabetic Patients with the Loss of Protective Sensation" (Kimberly Anderson, M.S. Thesis, Colorado School of Mines), reports measurements of temperatures, in °F, of both feet for 181 diabetic patients. The results are presented in the following table.
