Concept explainers
To identify: The number of parameters in the given multiple regression model.
Answer to Problem 29.31CYS
Correct answer:
Option (a): 4.
Explanation of Solution
Reason for correct answer:
The problem deals with the treadmill display showing the calories per hour by speed for a 175-pound male who is running on a Cybex treadmill, and it is inclined at 0%, 2%, and 4%.
The explanatory variables are given below:
The parameters used in the given problem are 4, which is defined as follows:
Thus, there are 4 parameters in the given multiple regression model.
Reason for incorrect answers:
Option (b): 5.
The given options suggest that there are 5 parameters in the given regression model.
By using the theory of multiple regression, it is identified that there are only 4 parameters given in the model. Thus, the given option is incorrect.
Option (c): 6
The given option suggest that there are 6 parameters in the given regression model.
By using the theory of multiple regression, it is identified that there are only 4 parameters given in the model. Thus, the given option is incorrect.
Thus, the options (b) and (c) are incorrect.
Conclusion:
Thus, there are 4 parameters in the given multiple regression model.
