CHAPTER 7 THE TWO-VARIABLE REGRESSION MODEL: HYPOTHESIS TESTING QUESTIONS 7.1. (a) In the regression context‚ the method of least squares estimates the regression parameters in such a way that the sum of the squared difference between the actual Y values (i.e.‚ the values of the dependent variable) and the estimated Y values is as small as possible. (b) The estimators of the regression parameters obtained by the method of least squares. (c) An estimator

CHAPTER 12 PRICING DECISIONS AND COST MANAGEMENT 12-1 The three major influences on pricing decisions are 1. Customers 2. Competitors 3. Costs 12-2 Not necessarily. For a one-time-only special order‚ the relevant costs are only those costs that will change as a result of accepting the order. In this case‚ full product costs will rarely be relevant. It is more likely that full product costs will be relevant costs for long-run pricing decisions. 12-3 Two examples of pricing decisions with

Advantages and disadvantages of variable costing Many managers use variable costing for internal reporting and decision making since it has number of advantages (Myers par. 1). First‚ on variable costing reports costs are organized by behavior which makes it easier to understand. Also‚ variable costing statements facilitate cost volume profit (CVP) analysis because it separates cost behavior by fixed and variable. Under variable costing‚ changes in inventory or production do not affect the

costs at the original budgeted activity level. True False 3. The overhead spending variance and the overhead efficiency variance are useful only if variable overhead really should be proportional to the activity measure that is being used in the flexible budget. True False 4. The variable overhead efficiency variance reflects how efficiently variable overhead resources were used. True False 5. A reason for keeping a constant denominator activity level is to maintain stability in the amount of

The structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic

Chapter 7 Variable Costing: A Tool for Management Solutions to Questions 7-1 The basic difference between absorption and variable costing is due to the handling of fixed manufacturing overhead. Under absorption costing‚ fixed manufacturing overhead is treated as a product cost and hence is an asset until products are sold. Under variable costing‚ fixed manufacturing overhead is treated as a period cost and is charged in full against the current period’s income. 7-2 Selling and administrative expenses
