Translate the statement into a confidence interval. Approximate the level of confidence. In a survey of 1007 parents of children ages 8-14, 75% say they are willing to get a second or part-time job to pay for their children's college education and 45% say they lose sleep worrying about college costs. The survey's margin of error is ±3%. The confidence interval for the proportion is (0.72, 0.78) (Round to three decimal places as needed.) Use the results from the survey about getting a second or part-time job. The interval is a 97.2 % confidence interval. (Round to one decimal place as needed.) Use the results from the survey about losing sleep. The confidence interval for the proportion is (0.42,0.48). (Round to three decimal places as needed.) A Use the results from the survey about losing sleep. The interval is a % confidence interval. (Round to one decimal place as needed.) GREER
