Problem of the Week #10 (POTW#10):
An economist was interested in modeling the relationship among annual
income
, level of education, and work experience. The level of education is the
number of years of education beyond eighth grade, so 1 represents
completing
1 year of high school, 8 means completing 4 years of college, and so on.
Work experience is the number of years employed in the current profession.
From a random sample of 12 individuals, this economist obtained the
following data:
Work Experience (years) Level of Education Annual Income ($ thousands)
12 6 34.7
14 3 17.9
4 8 22.7
16 8 63.1
12 4 33.0
20 4 41.4
25 1 20.7
8 3 14.6
24 12 97.3
28 9 72.1
4 11 49.1
15 4 52.0
Required:
(a) Please state the regression equation corresponding to the above
scenario.
(b) Please conduct a regression analysis of these data. Be sure to
include (e.g., copy and paste) your relevant regression output as part of
your response.
(c) What can you conclude regarding the relationship among annual income,
level of education and work experience based on your regression analysis
results in part (b)? Be sure to cite relevant numeric indices or results of
your regression analysis as part of your response. | h**********g

In the case where 楼主是美女，it is not 作弊!
In all other cases，it is 作弊!
In this particular case, we don't know for sure, but most likely it is 作弊.
