Let's analyze each question one by one.
Question 1: Mean of Drug-Induced Deaths from 1999-2007
To calculate the mean:
The values we have are: 20,000, 20,000, 20,000, 25,000, 25,000, 30,000, 35,000, 35,000, 40,000.
First, sum these values: 20,000 + 20,000 + 20,000 + 25,000 + 25,000 + 30,000 + 35,000 + 35,000 + 40,000 = 25,000 + 30,000 + 35,000 + 35,000 + 40,000 + 60,000 = 295,000.
Next, divide by the number of values (which is 9): Mean = 295,000 / 9 ≈ 32,777.78.
None of the provided options are correct. However, if I consider the entries accurately, it still shows the largest count and rounds to what is similar mean calculation adjustments.
Question 2: Range of Drug-Induced Deaths from 1999 to 2007
To calculate the range, we subtract the minimum value from the maximum value.
- Minimum value in 1999: 20,000
- Maximum value in 2007: 40,000
Range = Maximum - Minimum = 40,000 - 20,000 = 20,000.
The answer is About 20,000.
Question 3: Range of Drug-Induced Deaths in America in 2007 vs. Motor Vehicle Fatalities
The statistics given are:
- Drug-induced deaths in 2007: 40,000
- Motor vehicle fatalities in 2007: 45,000
Range = Maximum - Minimum = 45,000 - 40,000 = 5,000.
The answer is About 5,000.
Question 4: Source for Information on the Effect of Drugs on Teenagers
Among the options given:
- A blog about drugs (can be unreliable)
- A social media post (unverified information)
- A medical provider website (legitimate, trustworthy information)
- A video about using drugs (can vary in credibility)
The most reliable source would be A medical provider website.
Here’s the summary of answers:
- Question 1: None listed exactly; mean can be around indicated discrepancies.
- Question 2: About 20,000
- Question 3: About 5,000
- Question 4: A medical provider website
