Question
I need the answers for the wrong problems been struggling for a while
According the April 12, 2017 Pew Research survey, 58% of Americans approve of U.S. missile strikes in Syria in response to reports of the use of chemical weapons by Bashar al-Assad's government (the Syrian government). A sample of 50 Americans are surveyed. Let p be the sample proportion of Americans who approve the U.S. missile strikes. 1. What is the population proportion? 58 v (decimal form) 2. What is the sample size? 50 3. Can the normal approximation be used with this distribution? Yes, the sample distribution méets the "rule of thumb." v 4. What is the mean of the sampling proportion? 0.58 5. What is the standard deviation sampling proportion? .0049 x (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? o What is p? 0.5 1:29 A 12/8/20
