a.
To construct: A
b.
To fit: A multiple regression model using the listed variables for predicting calories burnt.
c.
To check: Whether the model provides a better fit for the given data.
Answer:
The model provides a better fit for the given data.
Explanation:
Justification:
R-square:
The R-square is a multiple correlation coefficient and it is the square of correlation between the observed response variable and predicted response variable.
R-square tells about the fit of the model. If the R-square value is high then the model fits better.
From the MINITAB output it can be seen that the R-square value is 98.62%. This tells that the explanatory variables could explain 98.62% of variation in predicting the calories burnt.
d.
To find: Whether there is any significant differences in the relationship between the calories burnt and speed for two treadmills.
