A manufacturing plant has two assembly lines for producing plastic bottles. The plant manager was concerned about whether the proportion of defective bottles differed between the two lines. Two independent random samples were selected and the following summary data computed: Perform the appropriate test of hypothesis using = 0.05.
Test statistic = ______________
Critical Value(s) = ______________
Conclusion: ______________
Interpretation: __________________________________________
Assembly Lines
Manufacturing processes in which parts are added to a product in a sequential manner using optimally planned workflows to create a finished product much faster than with traditional methods.
Test Statistic
A value calculated from sample data during a hypothesis test used to determine whether to reject the null hypothesis.
Critical Value
A threshold value that defines the boundary of the rejection region in hypothesis testing, beyond which the null hypothesis is rejected.
- Compute the test statistic to compare proportions across two populations.
