You have fit a regression model with two regressors to a data set that has 20 observations. The total sum of squares is 1000 and
Llana [10]

Answer:

Hence the adjusted R-squared value for this model is 0.7205.

Step-by-step explanation:

Given n= sample size=20  

Total Sum of square (SST) =1000  

Model sum of square(SSR) =750  

Residual Sum of Square (SSE)=250  

The value of R ^2 for this model is,  

R^2 = \frac{SSR}{SST}  

R^2 = 750/1000 =0.75  

Adjusted R^2 :

Adjusted R^2 =1- \frac{(1-R^2)\times(n-1)}{(n-k-1)}

Where k= number of regressors in the model.

Adjusted R^2 =1-(19\times 0.25/((20-2-1)) = 0.7205

Margo borrows $2000, agreeing to pay it back with 8% annual interest after 6 months. How much interest will she pay?Round your a
Amiraneli [1.4K]

Principal of the loan = $ 2,000

Interest rate = 8% annually or 0.08

Period of the loan = 6 months or 1/2 year

For calculating the interest that Margo will pay, we use the simple interest formula, this way:

Interest = Principal * interest rate * period of the loan

Replacing with the values we know:

Interest = 2,000 * 0.08 * 0.5

Interest = $ 80

Interpretation

Margo will pay $ 80 of interest for the loan after 6 months
