3. No, requirement that np(1-p) greater than 10 not satisfied
4. No, sample size no more than 5% not satisfied
C. 95% confidence interval is (_,_) (3 decimal places as needed)
D. Interpret the confidence interval
1. True value of p will fall with interval
2. True value of p will not fall
3. Interval contains true value of p
