a. Does the distribution of , the sample proportion of adults who list recycling as the leading way to help the environment have an approximate normal distribution? If so, what is its mean and standard deviation?
b. What is the probability that the sample proportion is less than 75%?
c. What is the probability that lies in the interval .7 to .75?
d. What might you conclude about p if the sample proportion were less than .65?
