Transcribed Image Text:Part 1:
A large mortgage company, House4U, has been tasked by the CEO to reduce the amount of time it takes
to approve new applications for mortgage loans. The approval process must go through formal
underwriting, which includes a review of the application and obtaining and reviewing the following:
credit bureau report, pay stubs, copies of tax returns, additional work history information, bank
statements and other asset information, title search, and the property appraisal.
You are hired as a consultant and begin by collecting the data needed to begin your analysis. You select
a random sample of 36 mortgage loans which were approved during the last month. You calculate the
sample mean and standard deviation in Excel (Use the dataset called "Approval_time.xlsx" in Problem
Set #2 Folder).
