Multiple Choice

TABLE 11-11
A student team in a business statistics course designed an experiment to investigate whether the brand of bubblegum used affected the size of bubbles they could blow.To reduce the person-to-person variability,the students decided to use a randomized block design using themselves as blocks.
Four brands of bubblegum were tested.A student chewed two pieces of a brand of gum and then blew a bubble,attempting to make it as big as possible.Another student measured the diameter of the bubble at its biggest point.The following table gives the diameters of the bubbles (in inches) for the 16 observations.
-Referring to Table 11-11,the null hypothesis for the randomized block F test for the difference in the means is

• A)H₀ : μ_A = μ_B = μ_C = μ_D
• B)H₀ : μ_Kyle = μ_Sarah = μ_Leigh = μ_Isaac
• C)H₀ : M_A = M_B = M_C = M_D
• D)H₀ : M_Kyle= M_Sarah = M_Leigh = M_Isaac

Definitions:

Fixed Manufacturing Overhead

Expenses related to manufacturing that remain constant regardless of the level of production, such as building lease payments and equipment depreciation.

Deferred Inventories

Inventory costs that are not expensed in the period they are incurred but are deferred to a future period.

Absorption Costing

This accounting practice involves adding all costs associated with production, including direct materials, labor, and both kinds of overhead expenses (variable and fixed), into the cost calculation of a product.

Unit Product Cost

The total cost (fixed and variable) associated with making one unit of product.
