WHAT IS A RANDOM VARIABLE? A random variable assigns a number to each outcome of a random circumstance‚ or‚ equivalently‚ a random variable assigns a number to each unit in a population. It is easier to create rules for broad classes of situations and then identify how a specific example fits into a class than it is to create rules for each specific example. We can employ this strategy quite effectively for working with a wide variety of situations Involving probability and random outcomes. We

1) When will profits reported under variable and absorption costing differ? How can we reconcile the profits reported under the two approaches? Profits reported under variable and absorption costing will differ when inventory increases or decreases during the year. The difference involves the timing with which fixed manufacturing overhead becomes an expense. Under variable costing‚ fixed overhead is expensed immediately as it is incurred. Under absorption costing‚ fixed overhead is inventoried

THE MOMENTS OF A RANDOM VARIABLE Definition: Let X be a rv with the range space Rx and let c be any known constant. Then the kth moment of X about the constant c is defined as Mk (X) = E[ (X c)k ]. (12) In the field of statistics only 2 values of c are of interest: c = 0 and c = . Moments about c = 0 are called origin moments and are denoted by k‚ i.e.‚ k = E(Xk )‚ where c = 0 has been inserted into equation (12). Moments about the

The Case of the Variable Laminates The Case of the Variable Laminates Grantham University Experimental design is “a formal plan that details the specifics for conducting an experiment‚ such as which responses‚ factors‚ levels‚ blocks‚ treatments‚ and tools are to be used” (Sower 2010). An experiment where one variable is studied while the other variables are held constant can be inefficient and suffers from the inability to assess interactions among the variables as well as the interaction
