Johnsbi bas nsl 1.13 Show that o²= [ (x – µ)² ƒ(x) dx = | x² f(x) dx – µ² %3D 1.14 For the geometric distribution, show that p(x) = 1 and derive the expression for F(x). %3D x=1 26 ms Hint: Use the geometric series. 1.15 One approach for estimating parameters of a distribution is known as the method of moments. Consider for example the rectangular distribution where f(x) = 1/(b – a), a <x< b. By setting the sample mean x (first moment) and sample variance s2 (2nd moment about the mean) equal to the distribution's mean and variance expressed in terms of its parameters a and b, the two equations can be solved simultaneously for their values.
