Answer:
(A) A scatter plot is used to determine if the linear model is appropriate.
(B) A linear model estimates the value of the dependent variables.
Step-by-step explanation:
The regression model is formed to estimate the Wingspan using the bird's Height when perched.
The model is of the form:
[tex]Wingspan=\beta Bird's\ height\ + \alpha +\epsilon[/tex]
(A)
The R squared value is a statistic that is used to determine the proportion of variation in the dependent variable that can be explained by the independent variables.
R squared value of 93% indicates that 93% variation in the Wingspan is explained y the bird's height when perched.
To determine whether the linear model is appropriate one could use a scatter plot. A scatter plot is used to determine whether the provided data is representing the linear relation between two variables.
(B)
The regression model is:
[tex]Wingspan=\beta Bird's\ height\ + \alpha +\epsilon[/tex]
This model is used to estimate the wingspan for any provided bird's height.
It does provided an accurate value of the dependent variable.
Thus, a bird with height 10 inches can have an estimated wingspan of 17 inches.
