Question

A company that produces snack foods uses a machine to package 454g bags of pretzels. The hypotheses are
as follows: Ho : µ = 454g (the packaging machine is working properly)
Ha : µ ≠ 454g (the packaging machine is not working properly)
Suppose that the results of the sampling lead to non-rejection of the null hypothesis. Classify the conclusion as
a Type I Error, Type II Error, or a correct decision, if in fact the mean net weight is not equal to 454g.

Answer 1

A type I error can only occur if the null is rejected and the null is true (not the case here)

 

A type II error fails to reject a false null (this is the case here)

 

The last sentence states : if in fact the mean net weight is not equal to 454g

 

and your analysis lead to a non-rejection

 

This is a TYPE II error
