The following estimated regression equation based on 30 observations was presented. ŷ = 17.6 + 3.8x1 − 2.3x2 + 7.6x3 + 2.7x4 The values of SST and SSR are 1,803 and 1,756, respectively.
(a) Compute R2. (Round your answer to three decimal places.) R2 =
(b) Compute Ra2. (Round your answer to three decimal places.) Ra2 =
(c) Comment on the goodness of fit. (For purposes of this exercise, consider a proportion large if it is at least 0.55.)
The estimated regression equation provided a good fit as a large proportion of the variability in y has been explained by the estimated regression equation.
The estimated regression equation did not provide a good fit as a small proportion of the variability in y has been explained by the estimated regression equation.

Answers
Answer:
a) = 0.9739
b) = 0.969
c) option A is correct
Step-by-step explanation:
Given that:
sample size n = 30
SST = 1803
SSR = 1756
[tex]R^2 = \dfrac{SSR}{SST} \\ \\ R ^2 = \dfrac{1756}{1803} \\ \\ \mathbf{R^2 =0.9739}[/tex]
The adjusted [tex]R_a^2[/tex] is computed as:
[tex]R_a^2 = 1 - (\dfrac{n-1}{n-p})(1-R^2)[/tex]
where;
[tex]p = k+1 \\ p= 4+1 = 5[/tex]
[tex]R_a^2 = 1 - (\dfrac{30-1}{30-5})(1-0.9739)[/tex]
[tex]R_a^2 = 1 - (\dfrac{29}{25})(0.0261)[/tex]
[tex]R_a^2 = 1 - (1.16)(0.0261)[/tex]
[tex]R_a^2 = 1 -0.030276[/tex]
[tex]\mathbf{R_a^2 \simeq 0.969}[/tex]

What transformation has changed the parent function f(x) = (.5)* to its new
appearance shown in the graph below? (1 point)
Answers
Answer:
Vertical compression by a factor of ¼Step-by-step explanation:
[Transformed] f(x) = ¼(.5)ˣ
[Original] f(x) = (.5)ˣ
____________________
I determined this transformation by comparing the notable points on the graph.
When x = -2 for the original function f(x), y = 4.
For this transformed graph y = 1 instead of 4.
Therefore y is scaled by ¼, and so that is the vertical compression.
Put this numbers from least to greatest.
