Problem: Use random samples to predict the proportion of flowers in the field.
Appropriate Grade Level: 10 - 14.
Activity: Students will simulate taking random samples of different sizes in order predict the population proportion.
Questions to investigate:
How does the result compare to the expected value of the population proportion (p') and the standard deviation (the square root of (p'q'/n).
How does the sample size (n) affect the prediction of the population proportion?
How does the value of the population proportion affect the prediction of the population portion?
