Expert Solution

Points are represented as (x,y). The datapoints are :

The points are plotted in excel and the in-built regression function is used to find the equation. The equation is displayed on the chart itself. The dotted line is fitted line.

Manual calculations based on least fit criteria

Both the equations are same.

9. A line passing through the origin is described by the equation y = Mx, where M greater than or equal to 0 is a random slope. Let (theta) be the angle between this line and the horizontal axis, in the right side of the plane. Suppose that theta is uniformly distributed between 0 and 90 degrees (0 and pi/2 radians). What, then, is the pdf of M? What is the expected value of M?
