Find a transformation of that will give it a mean of zero and a variance of one (ie.‚ standardize ). Let the transformed variable be named Z. We desire μz=0‚ σ2z=1. This means 0=a+b μX and b2 σ2X=1. One solution to this system of equations is b=1/12 and a=-5/2. Of course‚ if you recognized the fact that our standard

CB has just experienced a 15 % decline in sales‚ due to the economic situation. In year 8‚ CB sold 3‚400 units. This flexible budget is allowing 110 more units be added into the mix. Although sales trends have remained consistent‚ despite the decline in sales from professional riders‚ it might

After squaring minus each variable is divided by the variance of that variable. And finally‚ all these four variances are added together and divided by 4. 2.

The variances are to be classified into controllable and uncontrollable variances. Standard costing is applicable only for controllable variances. For instance‚ if the industry changed the technology then the system will not be suitable. In that case‚ we will have to change or revise the standards. A frequent revision of

standards are set too high. When the products are run at a lower cost than the standard‚ then this produces a favorable variance. The cost of goods sold and variance should net to the correct cost though and this is the reason the system creates the variance. Lansing set a loose standard which the standard quantities and standard price are high‚ flowing this situation favorable variances will ordinarily result from operations. When the standard cost set artificially high‚ the standard cost of goods sold
