Question 3

# data[].attributes.attachment_link.readable_text
The table below shows the percents of U.S. citizens who had ever consumed a certain brand-name soda, out of all soda consumers, for each year from 1986 through 2006.

3.

The figure below shows a scatterplot of the data in the table and solid lines that are possible models for the data. Which of the 5 lines appears to be the best representation of the data?

Correct Answer: D

Explanation:

D Look at the graph. Line D roughly approximates the scatterplot, beginning and ending at the same values. Thus, Line D most closely matches what would be the ideal average line of the scatterplot data. Line E is completely above the scatterplot, and Line C is completely below it. Lines A and B don't come close to matching the diagonal scatterplot line.

Question 2

# data[].attributes.attachment_link.readable_text
The table below shows the percents of U.S. citizens who had ever consumed a certain brand-name soda, out of all soda consumers, for each year from 1986 through 2006.

2.

Which of the following years had the LEAST increase in the percent of U.S. citizens who had consumed the brand-name soda from the previous year?

Correct Answer: G

Explanation:

G From 1997 to 1998 the percent of U.S. citizens who had consumed the soda rose from 57.8% to 58.2%, 58.2 - 57.8 = 0.4%, which is the smallest increase among the years listed. If you picked choice (J), be careful-(J) gives the LARGEST increase. You're looking for the smallest.

Question 1

# data[].attributes.attachment_link.readable_text
1. The table below lists the number (to the nearest 1,000) of book club members in the United States for 2001 through 2004. Of the following expressions with x representing the number of years after 2001, which best models the number of book club members (in thousands) in the United States?

A. 539 x + 2,001
B. x + 2,001
C. x + 539
D. 547 x + 2,004
E. 2,001 x + 539

Correct Answer: C

Explanation:

C You can eliminate answer choices by substituting the number of years after 2001 for x. If you substitute 3 for x, you should get approximately 547 because 3 years after 2001, in 2004, there were 547,000 book club members. Choice (C) gives (3)+539=547, eliminating choices (A), (B), (D), and (E). Note that these choices all confuse years with actual values in the problem (the year 2001 becomes 2,001 in choices (A), (B), and (E), for example)-make sure you are reading carefully and not falling into these traps.
