Question: (50%)
During the year of 2001, in the US residential lenders were saturated in refinancing. The total mortgage packages approved exceeded $1.5 trillion. However, refinancing was not homogeneous across the US. Twenty major mortgage institutions were randomly selected, and the total refinancing was recorded for 2001 and 2000 (data are in the "QMCoursework-data" spreadsheet).
- Do the data support the hypothesis that there is a linear relationship between the amounts in each year?
- Is any observation influential?
