Question

in statistics, it is important to characterize your population and understand your sample. if your goal in a study is to analyze the number of teenage drivers using cell phones while driving, what would be an inappropriate population? 100 high school students who drive to school on a daily basis 50 girls from a local high school 200 high school students 100 high school juniors with their licenses

Explanation:

The study is about teenage drivers using cell - phones while driving. The population should be related to teenage drivers.

• Option 1: 100 high - school students who drive to school daily are teenage drivers.
• Option 2: 50 girls from a local high - school may not all be drivers.
• Option 3: 200 high - school students may not all be drivers.
• Option 4: 100 high - school juniors with their licenses are teenage drivers.

Since the study is about teenage drivers, a population that may not include drivers (like just high - school students or just girls from a high - school without specifying they are drivers) is inappropriate. Among the options, 200 high - school students is the most inappropriate as it is the least specific about being drivers compared to the other options (options 1 and 4 clearly mention drivers, option 2 is gender - specific but still not about drivers as clearly as options 1 and 4).

Answer:

200 high school students
