Document Summary
Proper blending of fine and coarse powders prior to copper sintering is essential for uniformity in the finished product. One way to check the homogeneity of the blend is to select many small samples of the blended powders and measure the proportion of the total weight contributed by the fine powders in each. These measurements should be relatively stable if a homogeneous blend has been obtained. a suppose that the proportion of total weight contributed by the fine powders has a beta distribution with = = 3. Find the mean and variance of the proportion of weight contributed by the fine powders. A random variable y is said to have a beta probability distribution with parameter. , if and only if the density function of y is: Given that the proportion of total weights contributed by the fine powder has a beta distribution with and.
