Expert Solution

If you see the table, there are 8 observations, which were used for regression analysis, so

NO OF DATA POINTS = No of observations = 8

Answer : 8

In python- Create a class defined for Regression. Class attributes are data points for x, y, the slope and the intercept for the regression line. Define an instance method to find the regression line parameters (slope and intercept). Plot all data points on the graph. Plot the regression line on the same plot.
