2-Sample Proportion Test Exercise
Data File: N/A
A mortgage company performs reviews of its closing documents prior to the closing dates. This review may prompt changes or document additions that should have been in the closing package. Any closing package found with inaccuracies or known to be incomplete is deemed defective and requires rework prior to closing. In the prior calendar year, the defective rate for these reviews was 17.99% (783 defective packages out of 4,352 reviewed). During the current year, the year-to-date defective rate is 21.15% (180 of 870). Use the information provided to perform a 2-sample proportion test to determine if there is a difference between the current satisfaction rate and that of the prior year.
Question:
Is there a difference between the current satisfaction rate and the prior years satisfaction rate?
