Question 5 1 I 1 pts In 2006, the General Social Survey (which is conducted uses a method similar to simple random sampling) included a question that asked, "Do you see yourself as someone who has an active imagination?" For this question, 448 people said that they definitely did out of 1506 randomly selected people. What is the 95% confidence interval for the proportion of all Americans who believe that believe that they have an active imagination? (0.267, 0.328) - E - (0.274, 0.321) Assumptions are not met. Can not make confidence interval. (0.263, 0.332) Remember that you have to have at least 15 observed successes and 15 observed failures. The formula for the confidence interval is phat +/- z * sqrt(phat *(1-phat))
