Is the environment a major issue with Canadians? To answer that question, a researcher conducts a survey of 1,255 randomly selected Canadians Suppose 710 of the sampled people replied that the environment is a major issue. Construct a 95% confidence interval to estimate the proportion of Canadians who feel that the environment is a major issue. What is the point estimate of this proportion? "(Round the intermediate values to 3 decimal places, e g. 0.759. Round your answer to 3 decimal places, eg. 0.759) *(Round your answer to 3 decimal places, eg. 0.759J ss. The point estimate is
