A manufacturing process produces bags of cookies The weights of these bags are known to be Normally distributed and should have
a mean of μ = 15.0 ounces with a standard deviation of σ = 0.4 ounces. In order to monitor the process, four bags are selected periodically and their average weight (x¯¯) is computed. What is the parameter of interest?
The parameter of interest is average weight of the bags of cookies sampled.
Step-by-step explanation:
Sampling is done to compare sample average weight against the known average weight. (μ = 15.0 ounces) and to check if the manufacturing process produces bags as expected.
Then A hypothesis test can be done to test if average weight μ is 15.0 ounces by assuming <em>null</em> and <em>alternative</em> hypotheses at a <em>significance level</em>.
As a result, the purpose is to make an estimation about the average weight of the bags produced in the manufacturing process.
