According 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 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? 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 minimizing air 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 in minimizing air pollution? (decimal form)

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
