The frequency table below shows the hourly wages of 22 factory workers. How many are paid $10.50 per hour or more?
$7.50–$8.49 1
$8.50–$9.49 4
$9.50–$10.49 6
$10.50–$11.49 7
$11.50–$12.49 4

There are 7+4=11 workers who are paid less than $10.50 per hour. Therefore, there are 22-11= <<22-11=11>>11 workers who are paid $10.50 per hour or more.
Answer: \boxed{11}.
The Beevillie City Council surved 500 Beeville citizens. Of those surveyed, 350 citizens named summer as their favorite season. Based on survey results, how many of the 36,500 Beeville citizens would most likely name summer at their favorite season?
If 350 out of 500 surveyed citizens like summer the most, we can set up a proportion:
$\frac{350}{500} = \frac{x}{36500}$
where $x$ represents the number of citizens out of the total population who like summer the most.
Cross-multiplying, we get:
$350 \cdot 36500 = 500 \cdot x$
Simplifying, we get:
$x = \frac{350 \cdot 36500}{500} = 25,550$
Therefore, out of the 36,500 Beeville citizens, approximately 25,550 would most likely name summer as their favorite season.
Answer: \boxed{25,550}.
A newspaper reporter wants to know how popular the hobby of bird watching is in the city. He asked people at local bird refuge if they watched birds as a hobby. Which of the following best explains whether the reporters data is valid or not?
The validity of the reporter's data depends on several factors:
1. Sample size: The reporter should survey a representative sample of the city's population to get accurate data on how popular bird watching is. If the sample is too small or not representative of the whole population, the data may be inaccurate.
2. Sampling method: The reporter should use a random sampling method to ensure that everyone in the city has an equal chance of being surveyed. If the sample is biased (e.g. only people who visit the bird refuge are surveyed), the data may be inaccurate.
3. Survey questions: The reporter should ask clear and unbiased questions to get accurate responses from the participants. If the questions are confusing or biased, the data may be inaccurate.
4. Response rate: The reporter should aim for a high response rate to ensure that the data is representative of the whole population. If many people refuse to participate or are unavailable, the data may be biased.
If the reporter ensures that these factors are taken into account, then the data collected from the people at the local bird refuge would be a valid representation of how popular bird watching is in the city. However, if any of these factors are overlooked or not addressed properly, the data collected may not be entirely valid or reliable.
Which of the following types of information is suited for display on a double line graph?
Double line graphs are best suited for displaying and comparing two sets of data that are related to each other over a period of time.
For example, a double line graph could be used to show the sales of two different products (Product A and Product B) over several months. The graph would have two lines, one for each product, and the x-axis would show the time periods (months) while the y-axis shows the number of units sold. By plotting the data for both products on the same graph, it would be easy to compare the sales trends for each product over time.
Another example could be comparing the temperature and precipitation for a certain location over several months. The graph would show two lines, one for temperature and one for precipitation, with the x-axis showing time and the y-axis showing temperature (in degrees Fahrenheit or Celsius) and precipitation (in inches or millimeters).
In general, double line graphs are best suited for showing trends or changes over time for two sets of data that are related to each other.

Barry asked 40 random students at his school to name their favorite ice cream flavor. of the 40 students he asked, 25 of them preferred chocolate. based on Barrys result, how many of the 1,200 students in the school most likely prefer chocolate ice cream?
If 25 out of 40 students surveyed preferred chocolate ice cream, we can set up a proportion:
$\frac{25}{40} = \frac{x}{1200}$
where $x$ represents the number of students out of the total population who prefer chocolate ice cream.
Cross-multiplying, we get:
$25 \cdot 1200 = 40 \cdot x$
Simplifying, we get:
$x = \frac{25 \cdot 1200}{40} = 750$
Therefore, based on Barry's survey, it can be estimated that 750 students out of the 1,200 students in the school most likely prefer chocolate ice cream.
Answer: \boxed{750}.
A sports reporter said that 2 out of every 3 people he talked to at the hometown baseball game named baseball as their favorite sport. the reporter claimed that baseball was the most popular sport in town. which of the following explains why the reporter's claim might not be true?
The reporter's claim that baseball is the most popular sport in town might not be true because of the following reasons:
1. Sample size: The reporter may have only talked to a small number of people at the game, and therefore, the sample may not be representative of the entire town's population. If the sample is too small, it may not be enough to make generalized conclusions about the town's preferences for sports.
2. Sample selection: The reporter may have only talked to baseball fans or people attending a baseball game. This would mean that the sample is not representative of the entire town's population and may overestimate the popularity of baseball.
3. Response bias: The way the reporter phrased the question may have influenced people's responses. For example, if the reporter asked leading questions such as "Don't you think baseball is the best sport?" or if they only interviewed people wearing baseball merchandise, it may have biased the results in favor of baseball.
4. Recall Bias: People's ability to recall their favorite sport might be biased due to recent events. For example, if the town's baseball team recently won an important championship, then people may be more likely to choose baseball as their favorite sport due to the vividness effect.
Therefore, the reporter's claim that baseball is the most popular sport in town should be taken with a grain of salt and cannot be fully trusted without further evidence and analysis.
