明天就要交的考试题，但这道题实在有些搞不明白，特别是第6和第7问，在线等求高手指点，不胜感谢。原始数据请参看附件。

1. Identify the type and classification of data for each variable.
2. Comment on Cars as being normally distributed using any and all appropriate analyses.

3. Is there a significant difference in the Savings between those with “high school only” educational level and those with “doctorate”?

4. Prepare a correlation matrix and comment on the relationships.

5. Is there a significant relationship between Savings and SCIndex?

6. What is the best single independent variable for predicting Salary based on the quantitative analysis and common senses rationale? Based on this analysis, what would you predict the salary to be for a couple with the following profile, undergrad education level, $86,000 combined salary, $42,000 worth of cars owned, $2,000 savings, a $140,000 home and a SCIndex of 2?

7. Determine the most parsimonious multiple regression model for predicting SCIndex and interpret your findings as a comment on social climbing ambition and personal financial management practices.
