25. (B). This question is an Analyze the

Argument Structure question; the best

approach is to identify the conclusion, and

then check each boldface portion of the

question for how it relates to the conclusion,

and eliminate incorrect answer choices on

that basis. Here, the second boldface is the

conclusion of the argument, as highlighted by

the use of the signal word Therefore.

(A) The first boldface is not an assumption,

as assumptions are, by definition, unstated.

Also, the second boldface does not just

a different strategy endorsed by the

argument, of charging less than the greatest

possible price to maximize profit.

(C) The first boldface is not an assumption,

as assumptions are, by definition, unstated.

The second boldface is not the strategy

referenced in the first boldface, as this

answer choice suggests.

(D) The first boldface does not demonstrate

that the strategy of selling for the greatest

price will not apply, but instead supports it.

Also, the second boldface is the arguments

conclusion itself, not a factor in support of it.

(E) The description of the first boldface is

accurate; however, the second boldface is

not a factor against the strategy of

maximizing profits by charging the greatest

possible price, but an alternative strategy

altogether.

47. 36.6. To calculate first findthe squared differencesbetween the average and theterms. For example, thedifference between the

average, 4, and the first term, -1, is 5. 5

2= 25. Do this for all

four terms.

47. 36.4. To calculate, first find the squareddifferences between the average and each ofthe terms. For example, there is a differenceof 4 between the average, which is 3, andthe first term, which is -1. The square of this

difference is 42 = 16. Repeat for the otherthree terms.


1: (4 (1)) = 5 = 25 -1: (3 (-1)) = 4 = 16


4: (4 (0)) = 4 = 16 4: (3 (4)) = (-1) = 1


30: (4 (30)) = (26) = 676 30: (3 (30)) = (-27) = 729


21: (4 (21))2

= (25)2

= 625 -21: (3 (-21))2

= (24)2

= 576


Add all of these terms together:25 + 16 + 676 + 625 = 1,342.

Add all of these terms together: 16 + 1+ 729+ 576 = 1,322.
