A straight line is fit to a data set (ln x, y). This line intercepts the abscissa at ln x = 0.1 and has a slope of −0.02. What is the value of y at x = 5 from the fit?

Expert Solution

Since the figure will be straight line having intercept 0.1 at abscissa and slope = - 0.02

Hence, equation of line

⇒ y = - m(ln x) + c

when x = 0.1, then y = 0

⇒ 0 = - 0.02(0.1) + c

⇒ c = 0.02

Now when x = 5

⇒ y = - m(ln 5) + c

⇒ y = - 0.02(1.6) + 0.02

⇒ y = - 0.032 + 0.02

⇒ y = - 0.030

∴ The value of y when x = 5 is -0.030.

Create a class defined for Regression. Class attributes are data points for x, y, the slope and the intercept for the regression line.

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.
