The result of the survey is that 136 of the 200 students responded "yes." An approximate 98% confidence interval is (0.603, 0.757). Complete parts a through d below. a) How would the confidence interval change if the confidence level had been 95% instead of 98%? The new confidence interval would be narrower. The new confidence interval would be (Round to three decimal places as needed.)
