Problem #1 :
-
Check for mismeasured X variables. Label this page
PAGE
1
Write the question above your answer.
- What are you doing in Minitab to check for mismeasured X’s and how are you using the output ..what are you looking at? With a highlighter pen, highlight what you’re looking at.
- Using the output shown what did you find, and what did you do in this situation with these data?
-
Check for multicollinearity on a new page labeled
PAGE
2.
Type each question with your answer.
- What are you looking at in the Minitab output, highlight it and how are you evaluating it?
- What does multicollinearity do to the regression that is bad?
- Put the output you used in this analysis below this on PAGE 2
-
Check for Curvilinearity and find the best model on new page or pages labeled
PAGE

.
Type each question with your answer-delete unnecessary output to save paper (like outliers and ANOVA-but do show regression output).
- Briefly, what did you do, what are you looking at in the Minitab output –show relevant output and how are you evaluating it? What were your results in this case? Use a highlighter to highlight your output showing what you’re looking at.
-
Use ONE of the regression outputs to TEST whether
Advertising
is curvilinearly related to Students
.
HIGHLIGHT THIS ANSWER.
Show the output right next to this test : Ho, Ha, Tc, Ttable , Stat. Conclusion . - Use a highlighter and highlight the BEST Model from your output.
-
Next, check for heteroscedasticity on new page or pages labeled
PAGE
5.
Type each question with your answer.
- What are you looking at in the Minitab output (SHOW all graphs) and how are you evaluating it? What were your results in this case?
- Use a highlighter and highlight the BEST model from your output.
- Put the output you used in this analysis –delete un-necessary parts of the output to save paper like outlies and anova—but do list all the models you ran and graphs you used.
-
Using the model from Part 4 above, check for normal error terms on new page labeled
PAGE

- Show the graph you are looking at in the Minitab output. How are you evaluating it. What were your results in this case?
- Why do we have to check these assumptions? What happens if they are not met (in general?)
- Show the Minitab regression output (highlight it) and interpret the 95% prediction interval for a campus that spends 4,000 dollars on advertising, that is not AOC accredited, located in California and has 10% unionized workforce.
8. Label Page 8. Reprint your BEST MODEL from 1-5 above. Under this : Tell what the CEO could do when locating new campuses in order to maximize enrollments (use each coefficient).
Problem #2:
- Interpret the coefficients in the regression (and inflection points where applicable). Show your calculations if you use any equation calculations.
- Predict and interpret this number: grade when the student has 20 minutes to take the exam and it is a Morning class.
- Test the Coefficient on ClassM (B=0, B not equal 0) and include Ho, Ha, Tc, Ttable, Stat Conclusion
