Answer: Option (3) b0 = 11.4118 (Rounded to 4 decimal places) is the correct answer.
Justification: The linear regression equation based on the data point is of the form y_hat = b0 + b1x where b0 = the yintercept and b1 = the slope.. It is obtained to be y_hat = 11.4118 0.2647 x where y_hat is the predicted value of the dependent variable and x is the given value of the independent variable. So, b0 = 11.4118, and as per the given options, option (3) is the correct one.
