Specifically, the educator speculates that therewill be a difference between the two conditions that will foster how comfortablestudents feel asking questions, but the educator is not sure which way the differencewill go. On a random basis, the educator divided a class of eighteen 4th graders intotwo different styles of "feedback" during activities in class: a positive feedback groupof nine children; and a negative feedback group of nine children in which studentsreceived negative feedback while conducting an activity in the class. The data arepresented below and represent the number of questions asked by students whilelearning the material in class.Positive FeedbackGroupX15Negative FeedbackGroupX₂2

Question Help ▼ Due to the popularity of instant messaging and social networking, informal elements such as emoticons (e.g., the symbol ":)" to represent a smile) and abbreviations (e.g., "LOL" for "laughing out loud") have worked their way into teenagers' school writing assignments. A survey interviewed 800 randomly selected teenagers by telephone on their writing habits. Overall, 421 of the teenagers admitted using at least one informal element in school writing assignments. Based on the survey results, construct a 99% confidence interval for the proportion of all teenagers who have used at least one informal element in school writing assignments. Give a practical interpretation of the interval. The 99% confidence interval is ( ). (Round to three decimal places as needed.)
