Kendall asked 40 randomly selected seniors at his high school about their plans after they graduated. 29 students said they planned to go to college. If there are 380 seniors at Kendall's high school, estimate the number who plan to go to college.

Answer 1

To estimate the number of seniors who plan to go to college, we can use a proportion:

29/40 = x/380

Simplifying this equation, we get:

x = (29 x 380) / 40
x = 276.5

Therefore, we can estimate that approximately 277 seniors at Kendall's high school plan to go to college.

Answer 3

You're welcome! Let me know if you have any other questions.

Answer 4

You are surveying students to find out their opinion of the quality of food served in the school cafeteria. You decide to poll only those students who buy hot lunch on a particular day. Is your sample random? Explain

Answer 5

No, this is not a random sample. Polling only the students who buy hot lunch on a particular day may produce a biased sample because it doesn't include students who bring their lunch from home or purchase food from vending machines or off-campus. The sample would only represent a specific group of students who choose to buy hot lunch on that particular day. Therefore, the results of the survey may not accurately reflect the opinion of the entire student population regarding the quality of food served in the cafeteria. To obtain a random sample, you would need to survey a representative group of students from the entire student population, not just those who buy hot lunch on a particular day.
