**Problem Statement**

Suppose a population proportion is 0.40, and 80% of the time when you draw a random sample from this population you get a sample proportion of 0.35 or more. How large a sample were you taking?

*(Round your answer to the nearest integer, e.g. 25.)*

**Solution**

n = [__] 

*Note: This problem requires calculating the sample size (n) that would give a specific probability of observing a sample proportion of 0.35 or more.*
