Customers complained that there was not 16 ounces of soda in the 16 ounce bottles. To investigate, 10 bottles were pulled at random from each of the three shifts for a total of thirty (30) bottles. By measuring the contents of the bottles will determine if there is a deficit in each of the bottles distributed to the consumers. The bottles were measured for the exact amount and found that the measurements ranged from 14.0 to 16.1 ounces per bottle. The median of the 30 samples was 14.8 with a standard deviation of 0.6907.
Each bottle was measured according to each shift and the readings are as follows:
First shift: 149.2 of the 160 required making a reading of 93.25% with a deficit of 6.75%
Second shift: 151.7 of the 160 required making a reading of 94.81% with a deficit of 5.19%
Third shift: 145.2 of the 160 required making a reading of 90.75% with a deficit of 9.25%.
Measurements are in ounces. Overall the three shifts accumulated resulted in 446.1 of the 480 ounces required making the average of 93% deficit. It is determined that the samples of the bottle taken were in fact not measuring up to the advertized size of 16 ounces.
This can be caused by a possible three reasons. 1) Machine is not set correctly to dispense exactly 16 ounces per bottle. Settings will have to be checked and verified per shift to verify correct dispensing. 2) Too much carbonation present interfering with dispensing correctly. Each shift will monitor for the amount of carbonation during dispensing. 3) Bottle alignment on line may be off causing partial amount of soda dispensing not entering the bottle. Each shift will monitor and document the bottles are correctly aligned for proper dispensing.
The following graph will show the specifics according to the information obtained and the testing conducted.
