Step-by-step explanation:
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.
The estimated regression equation provided a good fit as a small proportion of the variability in y has been explained by the estimated regression equation.

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]

a customer purchases windows for $15,000 using a credit card. If the interest is compounded monthly at a rate of 16% per year, how much interest will be charged at the end of three years?
Answer:
≈ $9164.35
Step-by-step explanation:
The future amount A is calculated as
A = P [tex](1+\frac{r}{n}) ^{nt}[/tex]
P is the Principle
r is interest rate
n is number of times per year compounding happens
t is the number of years
Here P = 15000 , r = 16% = 0.16, n = 12 , t = 3
A = 15000 [tex](1+\frac{0.16}{12}) ^{(12(3))}[/tex]
= 15000 ([tex](1.01333)^{36}[/tex]
≈ 24164.35
Interest paid = $24164.35 - $15000 = $9164.35
Answer:

Answer:
the first option
Step-by-step explanation:
it's the only one tht adds to 180
Answer:
49°, 59° and 72°
Step-by-step explanation:
Interior angles are supposed to add up to 180°
49+59+72=180° (correct set)
34+45+11= 90° (not correct set)
24+51+15= 90° (not correct set)
45+70+85 = 200° (not correct set)
hence the correct set is 49°, 59° and 72°
