Normal ApproximationAccording to the May 16,2017 report by Pew Research, 68% of US adults say solar energy is very effective in minimizing air pollution.A sample of 240 U.S adults are surveyed. Let p be the sample proportion of Americans who believe solar energy is very effective inminimizing 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?4. 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 156 U.S adults of the 240 surveyed believe solar energy is very effective in minimizingair pollution?What is p?(decimal form)What is the z-score?(Round to the hundredths place)What is the probability that no more than 156 U.S. adults of the 240 surveyed believe solar energy is very effective inminimizing air pollution?(decimal form)

Using this data set What is the standard error of the relevant distribution? Ignoring that the number of men in the 2012 Survey was about 17,675, and the number of women was about 18,634, assume the samples were 100 men and 100 women in each Survey My worked solution is: P1: men proportion change = 15.5/100 = 0.155 N1 = 100 P2: women proportion change = 57.9/100 = 0.579 N2 = 100 {[0.155 * (1 - 0.155) /] + [0.579 * (1 - 0.579) / 100]} = 0.0037 Standard Error = 0.0037 is this correct?
