C)3.93 
D)9.32

Quizplus · Accepted Answer

The intercept is the value of y when x is equal to 0. Using the regression equation y=0.82x+3.93, we can see that when x=0, y=3.93. Therefore, the intercept is 3.93. To find the intercept, we need to use the equation of the regression line: y = mx + b, where m is the slope and b is the intercept. Using a calculator or statistical software, we can find that the equation of the regression line for the given data is y = 0.76x + 3.93. Therefore, the intercept is 3.93, which corresponds to choice C.
