Let be the sample proportion of Americans who approve the U.S. missile strikes. 1. What is the population proportion? 2. What is the sample size? (decimal form) 3. Can the normal approximation be used with this distribution? 4. What is the mean of the sampling proportion? 5. What is the standard deviation sampling proportion? (Round to 4 decimal places.) 6. What is the probability that no more than 25 Americans of the 50 in the survey approve of the missile strikes? What is p? What is the z-score? (Round to the nearest hundredth.) 0.5)= What is the requested probability? P(p 7. What is the probability that more than 30 of the 50 Americans in the survey approved of the missile strikes? What is p? What is the z-score? (Round to the nearest hundredth.) What is the requested probability? P(p 0.6)
