3. A large beverage company would like to use statistical process control to monitor a newbottlingmachine designed to load liquid into 350-ml bottles. This company knows thatthe exact amountthe machine places in each bottle can naturally vary by a small amountbut does not have any more specific information about the process. The companyoperated this new machine under careful supervision, confident that the machine wasunder complete control, for 7 hours. Each hour, a sample of nine bottles was taken offthe line and the amount of liquid in each bottle was carefully measured. This is theresulting data:SampleSample Mean (ml) Sample Range (ml)350.850.6350.800.80.5351.20351.001.0350.620.8351.120.70.8351.50a. Where should the control limits be placed on a mean chart intended to monitorthismachine in the future, using the same sampling procedure that produced thisdata?b. Where should the control limits be placed on a range chart intended to monitorthismachine in the future, using the same sampling procedure that produced thisdata?C. A new sample is taken from the machine's output, and these are the exact weights ofliquid in each bottle: 349.21 ml, 352.12 ml, 350.14 ml, 350.82 ml, 350.07 ml, 350.10ml, 350.50 ml, 349.75 ml, and 349.90ml. According to the charts created in parts aand b of this question, does this sample indicate the process is in control?123 4567
