ABC sells nospill syrup in bottles Management is evaluating

ABC sells no-spill syrup in bottles. Management is evaluating four different machines with standard deviations of .006, .01, .022, and .04 ounces for Machines A, B, C, and D, respectively. The specification limit is s 11.95 and 12.05 ounces. Which machines should receive more detailed evaluation (which machines are statistically capable)?

Solution

Answer -  A and B

( CP= (USL – LSL)/6;

Machine A =(12.05 - 11.95)/6*0.006 = 2.78;

Machine B =(12.05 -11.95)/6*0.01 = 1.67;

Machine C = (12.05 -11.95)/6*0.022 = 0.7575;

Machine D = (12.05 -11.95)/6*0.04 = 0.417)
