Suppose you fit the​ first-order model y=β0+β1x1+β2x2+β3x3+β4x4+β5x5+ε to n=30 data points and obtain SSE=0.33 and R2=0.93. Complete parts a and b.       Question content area bottom Part 1 a. Do the values of SSE and R2 suggest that the model provides a good fit to the​ data? Explain.     A. No. Since R2=0.93 is close to​ 1, this indicates the model does not provide a good fit.​ Also, SSE=0.33 is fairly​ small, which indicates the model does not provide a good fit.   B. There is not enough information to decide.   C. Yes. Since R2=0.93 is close to​ 1, this indicates the model provides a good fit.​ Also, SSE=0.33 is fairly​ small, which indicates the model provides a good fit.

Suppose you fit the​ first-order model
y=β0+β1x1+β2x2+β3x3+β4x4+β5x5+ε
to
n=30
data points and obtain
SSE=0.33

Part 1
a. Do the values of SSE and
R2
suggest that the model provides a good fit to the​ data? Explain.
 
 
A.
No. Since
R2=0.93
is close to​ 1, this indicates the model does not provide a good fit.​ Also,
SSE=0.33
is fairly​ small, which indicates the model does not provide a good fit.
 
B.
There is not enough information to decide.
 
C.
Yes. Since
R2=0.93
is close to​ 1, this indicates the model provides a good fit.​ Also,
SSE=0.33
is fairly​ small, which indicates the model provides a good fit.

b. Is the model of any use in predicting​ y? Test the null hypothesis
H0: β1=β2=...=β5=0
against the alternative​ hypothesis: At least one of the parameters
β1, β2, ... , β5
is nonzero. Use
α=0.10.
