Each of three botanists made a hypothesis regarding specimens of a particular plant species:
- Botanist 1: Any individual specimen possessing the gene for curly stems has either the gene for long roots or the gene for purple flowers, or both.
- Botanist 2: Any individual specimen possessing the gene for long roots has either the gene for flat leaves or the gene for round seeds, or both.
- Botanist 3: No individual specimen that possesses either the gene for curly stems or the gene for flat leaves or both has the gene for purple flowers.

Among the conifers were 258 spruces and 112 pines, along with some cedars and other species. Most of the deciduous trees were oaks, but one in eight was a maple. Of the oaks, 65 percent were red oaks and 25 percent were white oaks. Of the maples, 20 percent were Japanese maples.

Throughout a certain decade in a European city, the mean monthly rents for studio apartments varied yearly, from a low of €804 to a high of €1,173. Those for one-bedroom apartments also varied yearly, from a low of €1,060 to a high of €1,497. But some individual studio apartments rented for as little as €420 in some years, and some one-bedroom apartments rented for up to €2,262. To visually assess how the ratio of mean monthly rents for studio apartments to those for one-bedroom apartments varied yearly over the decade, Maria requires a graph with the following characteristics. The graph will have two axes of equal length, with mean rents for one-bedroom apartments shown on the horizontal axis and mean rents for studio apartments shown on the vertical axis, and with the same scale on both axes. For each year, mean rents will be plotted as a point.
From the following options, choose for Horizontal axis a range for the points on the horizontal axis and choose for Vertical axis a range for the points on the vertical axis that together would satisfy Maria's requirements for the graph. Make only two choose, one in each column.

There are three different ways to score in basketball. A successful shot from beyond an arc drawn on the court is worth 3 points. Shots made from inside the arc are worth 2 points. If a player is fouled by another player, the fouled player may shoot "free throws," which are worth 1 point each. A certain team scored 45 points in a game. The team made twice as many 2-point shots as 3-point shots. How many free throws did the team make?
(1) The team attempted 12 free throws.
(2) Five-sixths of the team's free-throw attempts were successful.

For each of the 8 quarters of 2008-2009, the graph shows a Japanese electronics firm ́s total US sales (rounded to the nearest 1 million US dollars), and the change in the average value of US dollar in Japanese yen, where the change is expressed as a percentage of the dollar ́s value in the first quarter of 2008 (Q1 2008), to the nearest 1 percent. For any given quarter, this data may be used to convert total US sales to their Q1 2008 yen equivalent: a value directly proportional to that quarter ́s total US sales in Q1 2008 yen.
On the basis of the information provided, choose the option that created the most accurate statement.
Q1 2008 yen-equivalent sales were highest in ___(A)___ of 2009.
Q1 2008 yen-equivalent sales for Q4 2009 were __(B)____ Q1 2008 yen-equivalent sales for Q4 2008.
A retail store has 60 employees—full-time salespeople (FT sales), part-time salespeople (PT sales), and managers—in the proportions shown by the graph. Each full-time salesperson and each manager works the same number of hours per week; each part-time salesperson works exactly half that many hours per week.
The store wants the ratio of the total number of hours worked per week by full-time salespeople to the total number of hours worked by part-time salespeople to be 2:3 and wants to achieve this ratio without changing the number of managers or the number of hours each manager works per week.
Based on the information provided, choose creates the most accurate statement.
To achieve the desired ratio, the store could __(A)___ the number of full-time salespeople and ___(B)___ the number of part-time salespeople.
The designers of a video game hired 100 game testers to play the game to determine whether the level of difficulty was appropriate. Each of the 100 testers made at most 25 attempts to complete each of the game's 15 levels (Levels 1–15). When a tester completed a level, he or she then made no further attempts at that level. For each of the levels, the table shows, among the testers who completed the level, the total number of testers whose number of attempts to complete that level fell in various ranges.
For each of the following statistical measures, select Must be 20 or less for every level if, based on the information provided, the measure must be at most 20 for each of the 15 levels. Otherwise, select Could be greater than 20 for one or more.
Could be greater than 20.
The graph above shows the changes in major land cover types in the given five-state region from 1982 to 1997.

Choose the option that creates the most accurate statement based on the information provided.

A statistician reached the following conclusions about games between university soccer teams: Overall, a team playing on its home field has a 45% chance of a win, a 25% chance of a loss, and a 30% chance of a draw (a tied outcome). In the games where one or more goals are scored, the team that scores the first goal has a 55% chance of scoring it in the game's first half and a 45% chance of scoring it later in the game. When that team is the home team (i.e., a team playing on its home field), there is a 40% chance that the other team will score no goals at all, and therefore a 60% chance that it will score one or more goals.
Select for X and for Y two different outcomes such that the information provided explicitly includes the statistician's estimates of the probability that if X occurs, so will Y. Make only two selections, one in each column.
