- A statistician has to decide on the basis of a singleobservation whether the parameter θ of the density f(x) =⎧⎨⎩2xθ 2 for 0 < x < θ0 elsewhere equals θ1 or θ2, where θ1 < θ2. If he decides on θ1 when theobserved value is less than the constant k, on θ2 when theobserved value is greater than or equal to the constant k,and he is fined C dollars for making the wrong decision,which value of k will minimize the maximum risk?arrow_forwardFind the center of mass of the given system of point masses lying on the x-axis m1 = 1, m2 = 3, m3 = 2, m4 = 9, m5 = 5 x1 = 6, x2 = 10, x3 = 3, x4 = 2, x5 = 4arrow_forwardCalculate the center of mass, or balancing point, for the collection of single point masses m1=2 at x1=0 and m2=4 at x2=2.
