Question

Check the requirements for regression for the data set of actual and recorded inventory values for Aries Car Parts from Exercise 15.When the auditor examined the relationship, he noticed two outliers, for observations 1 and 25 (why are these outliers?). Careful double-checking made the auditor realize that he had misread the written records for both data points. The recorded parts inventory for observation 1 is actually $446.23, and for observation 25 is $584.04.Amend the data set accordingly, and repeat your analysis.
