Explanation:

Analyze the first claim

The first claim states: "80% of students prefer the new school app, based on a survey conducted among only students enrolled in technology classes."

• This survey targets a specific subgroup (technology classes) to make a claim about all students.
• This introduces Sampling Bias because students in technology classes are more likely to prefer a new app than the general student population.
• Therefore, this is a Misleading Report Claim.

Analyze the second claim

The second claim states: "85% of students are satisfied with the school's guidance services, based on a survey of 250 students randomly chosen from different classes and sports teams."

• The sample is randomly selected from diverse groups (different classes and sports teams).
• This helps ensure a Representative Sample of the student body.
• Therefore, this is a Valid Report Claim.

Analyze the third claim

The third claim states: "65% of students use the school's library resources regularly, with data collected from a random sample of 200 students representing various grades and extracurricular activities."

• The sample is random and represents various grades and activities.
• This creates a Representative Sample that avoids systematic bias.
• Therefore, this is a Valid Report Claim.

Analyze the fourth claim

The fourth claim states: "70% of students enjoy the school's new cafeteria menu, based on a survey conducted with a random sample of 300 students from all grades."

• The sample is randomly selected from all grades.
• This ensures every student has an equal chance of selection, creating a Representative Sample.
• Therefore, this is a Valid Report Claim.
