Question 2: Problem Statement: In the automotive manufacturing industry, ensuring consistent quality in production processes is crucial to meet customer expectations and maintain competitiveness. Your task is to perform Statistical Process Control (SPC) analysis on a dataset of dimensional measurements taken from automotive components and draw conclusions based on your analysis. Data: Below is a dataset of dimensional measurements (in millimeters, mm) collected from 30 automotive components produced in a manufacturing facility: 32.1, 32.2, 32.0, 32.3, 32.1, 32.2, 32.4, 32.3, 32.2, 32.1, 32.0, 32.1, 32.2, 32.3, 32.4, 32.2, 32.1, 32.0, 32.3, 32.1, 32.2, 32.1, 32.0, 32.3, 32.4, 32.2, 32.1, 32.0, 32.3, 32.2 1. Calculate Control Limits: - Compute the mean (X-bar) and standard deviation (σ) of the dimensional measurements. Determine the Upper Control Limit (UCL) and Lower Control Limit (LCL) using the mean and standard deviation. 2. Construct X-bar Chart: - Plot the dimensional measurements on a time-ordered X-bar chart. - Add the UCL and LCL lines to the chart. 3. Analyze the Chart: - Interpret the X-bar chart by examining the plotted data points relative to the control limits. - Identify any points that fall outside the control limits or exhibit unusual patterns. 4. Draw Conclusions: - Based on your analysis, make a decision regarding the stability of the manufacturing process. - Provide recommendations for further action if necessary.
