According to the May 15,201? report by Flevllr Research, 45% of US adults say solar energy is very effective in minimizing air pollution. A sample of 160 LLB adults are surveyed. Let ,3 be the sample proportion of Americans who believe solar energy is very effective in minimizing air pollution. 1. What is the population proportion? |:| [decimal form} 2. What is the sample size? |:| 3. Can the normal approximation be used with this distribution? . What is the mean of the sampling proportion? 5. What is the standard deviation of the sampling proportion? |:| {Round to 4th decimal place} 6. What is the probability that no more than ?6 LLS adults of the 160 surveyed believe solar energy is very effective in minimizing air pollution? What is 1?? E [decimal form] What is the z-score? |:| {Round to the hundredths place} What is the probability that no more than 3'6 LLB. adults of the 16? surveyed believe solar energy is very effective in minimizing air pollution? |:| {decimal form}
