Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary. Let x be the independent variable and y the dependent variable. (Note that if x = 2, then y = 7 and so forth. yhat is the predicted value of the fitted equation.)
x 2 4 5 6
y 7 11 13 20
Answer Choices
yhat = 0.15 + 2.8x
yhat = 3.0x
yhat = 0.15 + 3.0x
yhat = 2.8x
