Question:
A firm is developing big punching bags weighing 100 pounds for fighters and boxing lovers. During manufacture, bags are sampled at random. Each bag is weighed, and the result is X-T (X = observed weight, T = Target = 100). The recorded values are the number of pounds away from the desired label weight of 100 pounds (Ibs). Positive values represent bags weighing more than 100 pounds; negative values represent bags weighing less than 100 pounds. It is reasonable to believe that this data can be changed using the lognormal transformation.
Take note of the following guidelines when collecting this information:
Employ three standard error limits / or the equivalent.
To evaluate control, only utilize the following rules: points beyond the bounds, runs, trends, and alternating points (Rules 1-4).
Please conduct an appropriate analysis and then respond to the corresponding questions. Give answers as four decimal points (X.XXXX).
1)What is the Upper natural process limit for the transformed values?
2)What is the Lower natural process limit for the transformed values?
3)What is the Upper natural process limit for the original values?
4)What is the Lower natural process limit for the original values?
