For some problem, the distribution is described by a symmetric triangle that goes from x=0 to x=1. Using the fact that the total distance under the curve needs to equal 1, find the height at x=0.5. Sketch a picture of the distribution. From here, figure out the formula for the distribution (hint: write it in terms of one function from x=0 to x<0.5 and another from x>0.5 to x=1.) Use this information to construct and solve the integral you would need to figure out the average value of f(x) over that interval if f(x)=x^2.

Likelihood. Let X,,..., X, be an i.i.d. sample from a distribution with density function f(x, Ø) = {eif x > 0, if x <0 (2x Tif x >0 f(x, 0) = {0 where 0 > 0 is an unknown parameter. 1. Use method of maximum likelihood to find the estimator for 0. 2. Apply this formula to estimate 0 from the sample (0.5, 0.5, 1).

A random number generator will spread its output uniformly across the entire interval from 0 to 1 as we allow it to generate a long sequence of numbers. The results of many trials are represented by the density curve of a uniform distribution. This density curve appears in red in the given figure. It has height 1 over the interval from 0 to 1, and height 0 everywhere else. The area under the density curve is 1: the area of...
