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]
