1 A. Explain when the implementation of measurement uncertainty (error) uses descriptive statistical methods or the Gaussian method B B.Explain the importance or uncertainty of measurement (error)

Q1 Foot ulcers are 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 18 diabetic patients. The results are presented in the Table Q1. Table Ql: Measurements of temperatures, in °F of left foot Vs right foot for 18 diabetic patients Left Foot Right Foot Left Foot Right Foot 80 85 75 88 89 87 80 76 81 86 82 78 81 82 85 80 89 85 80 89 87 78 80 87 86 87 82 78 78 86 76 88 89 89 90 88 (a) Compute the least-squares line for predicting the right foot temperature from the left foot temperature. (b) If the left foot temperatures of two patients differ by 2 degrees, predict by how much would their right foot temperatures will differ. (c) Predict the right foot temperature for a patient whose left foot temperature is…

An analyst wants to know whether there is any significant difference in the measurement results produced by alternative method compared a reference method in determination of the concentration of vitamin C in vegetables. He analysed eight different test materials using the both methods and the results are shown below: Test if the alternative method provides compatible measurement results at significant level of 0.05. Given that ?? = 2.365. (? = 0.296)

Which of the following values results from the use of a statistical test? 1. The critical value 2. The obtained value 3. Type I error 4. Type II error
