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
22.5
D
m = [?]
Answer:
m = 4
Step-by-step explanation:
ABCD ~ QRST, therefore, their corresponding side lengths brae proportional. This implies that:
10/m = 22.5/9
Cross multiply
m*22.5 = 9*10
22.5m = 90
Divide both sides by 22.5
m = 90/22.5
m = 4

An unknown number y is 12 more than an unknown number x. The number y is also x less than 17. The equations to find x and y are shown below. y = x + 12 y = −x + 17 Which of the following statements is a correct step to find x and y? (4 points) Question 1 options: 1) Multiply the equations to eliminate y. 2) Write the points where the graphs of the equations intersect the x-axis. 3) Write the points where the graphs of the equations intersect the y-axis. 4) Add the equations to eliminate x.
Answer:
4) add the equations to eliminate x
Step-by-step explanation:
After adding the equations then you can use the value you found for y to substitute back into one of the equations in order to find x

monika has 3 1/4 cups of rice. each sushi roll she makes required 7/16 of cup of rice to make with the rice she has how many full sushi rolls can monika make
Answer:7
Step-by-step explanation: 3 1/4 is equal to 13/4. When dividing fractions, you switch the numerator and denominator in the second fraction and change the symbol to a multiplication symbol. You then multiply straight across and then divide the top number by the bottom number. The whole number is how many times you can divide it equally

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:
The future amount A is calculated as
A = P (1+\frac{r}{n}) ^{nt}(1+nr)nt
P is the Principle
r is interest rate
n is number of times per year compounding happens
t is the number of years
