the linear regression model for the data set below has an r^2 value of about 0.67.
what does this indicate?

a. about 67% of the differences in the populations can be explained by the regression line
b. about 67% of the predictions made using linear model are correct
c. about 45% of the differences in the populations can be explained by the regression line

about 67% of the differences in the populations can be explained by the regression line

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

26?
