I need the answers for the wrong problems been struggling for a while

Transcribed Image Text: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
