Problem 1 The data file for this problem contains 82 consecutive values for the amount of deviation (in .000025 inch units) from a specified target value that an industrial machining process at a large manufacturer produced under specified operating conditions. Thus in the data 0 means that the value was right on target and -3 means that the part produced measured .000075 inches below the target value. The plot below is a time series plot of this data. Time Series Plot of C1 30 20 6' 1o 0 -10 1 8 16 24 32 40 48 56 64 72 80 Index Describe the plot. Is this process characterized by only common causes or are there any special causes? Is there anything unusual about this data? What action would you take if any as a result of this plot
