Difficulty: Moderate

Concept notes: A cross-sectional study examines a population at a single point in time to assess the relationship between variables. In this case, Dr. Miele surveyed people of different ages on one day to determine if a high protein diet leads to increased muscle mass.

Common Mistakes: A common mistake is confusing a cross-sectional study with a longitudinal study, which follows the same individuals over a period of time.

Explanations: The study conducted by Dr. Miele is a cross-sectional study because it measures the eating habits and muscle mass of different age groups on a single day. This type of study does not follow the same individuals over time, which would be characteristic of a longitudinal study. The survey data collected on one day from various age groups provides a snapshot of the relationship between diet and muscle mass at that specific point in time.

Option Analysis:

Option A: An experiment would involve manipulating variables and observing the effects, which is not described in the scenario.
Option B: A cross-sectional study is correct because it involves measuring variables at a single point in time across different groups.
Option C: A case study typically involves an in-depth examination of a single individual or a small group, which is not the case here.
Option D: A longitudinal study would follow the same individuals over a period of time, which is not described in the scenario.
Option E: A double-blind study involves both the participants and the researchers being unaware of the treatment conditions, which is not relevant to the described survey.

The data provided indicates the following: - 30 people chose Action movies. - 25 people chose Comedy movies. - 20 people chose Drama movies. - 24 people chose Horror movies. Adding these numbers together: 30 (Action) + 25 (Comedy) + 20 (Drama) + 24 (Horror) = 99 Thus, the total number of participants in the survey is 99.

Option Analysis:

Option A: 75 is incorrect because it does not account for all the participants.
Option B: 78 is incorrect because it does not account for all the participants.
Option C: 99 is correct as it is the sum of all participants.
Option D: 101 is incorrect because it exceeds the sum of all participants.

7. A recent survey of 800 seventh graders from across the state shows 4 out of 10 like to play paper football. How many students said they like to play paper football?

Correct Answer: Correct answer is: (C) 320 students.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: The question involves calculating a proportion from survey data.

Common Mistakes: A common mistake is misinterpreting the fraction or percentage, leading to incorrect calculations.

Explanations: To find the number of students who like to play paper football, we need to calculate 4 out of 10 of the total number of students surveyed. 1. The total number of students surveyed is 800. 2. The fraction of students who like to play paper football is 4 out of 10, which can be written as 0.4. 3. Multiply the total number of students by the fraction: \( 800 \times 0.4 = 320 \). Thus, 320 students said they like to play paper football.

Option Analysis:

Option A: 40 students is incorrect because it is too low.
Option B: 200 students is incorrect because it is also too low.
Option C: 320 students is correct as calculated.
