Question

Problem 4 (40 points total) (Chapter 3) Administration at Muncie State University has compiled data of freshman applications versus tuition for 10 years as follows: Year 10 Freshman Applications 6050 4060 5200 4410 4380 4160 3560 2970 | 3280 3430 Annual Tuition 3600 3600 4000 4400 4500 5700 6000 6000 7500 8000 16 | 18 | 19 Table3 4a. Administration at State University believes that as tuition increases then freshman applications decrease. If you were to develop a trend analysis for annual tuition, what would be the independent variable? (I am looking for a "noun" here; I am not looking for a number). 10 points answer 4b. Administration at State University believes that the as number of freshman applications decrease then tuition increases. If you were to develop a trend analysis for number of freshman applications, what would be the independent variable? (I am looking for a "noun" here; I am not looking for a number). 10 points answer 4c. In part "b" above what is the sum of all 10 independent variables. I am looking for a number here. Add the sum of the 10 independent variables (from part "b') in Table 3 above. 10 points answer (go to two decimal places) 4d. Administration at State University believes that as freshman applications decrease then tuition increases. If you were to develop a linear regression model to determine if the administration beliefs are correct, what would your independent variable be? (I am looking for a "noun" here: I am not looking for a number answer Use space below and next page to show work, guesses do not count

Answer 1

4a.
Correct answer is : Annual tuition

Freshman applications here is dependent variable

4b. Correct answer is : Freshman applications

Annual tuition here is dependent variable

4c.

Sum of the 10 independent variables i.e freshmen applications =(6050+4060+5200+4410+4380+4160+3560+2970+3280+3430) = 41500

4d.

Correct answer is : Freshman applications

Annual tuition here is dependent variable
