Is the environment a major issue with Americans? To answer that
question, a researcher conducts a survey of 1255 randomly selected
Americans. Suppose 733 of the sampled people replied that the
environment is a major issue with them. Construct a 95% confidence
interval to estimate the proportion of Americans who feel that the
environment is a major issue with them. What is the point estimate
of this proportion?
