Question

Faculty members at Lowell Place High School want to determine whether there are enough students to have a Valentine's Day Formal. Eighty-eight of the 200 students said they would attend the Valentine's Day Formal. Construct and interpret a 90% confidence interval for p.
The 90% confidence interval is (0.4977, 0.5023). We are 90% confident that the true proportion of students attending the Valentine's Day Formal is between 49.77% and 50.23%.
The 90% confidence interval is (0.3823, 0.4977). There is a 90% chance that a randomly selected student who will attend the Valentine's Day Formal lies between 38.23% and 49.77%.
The 90% confidence interval is (0.4977, 0.5023). Ninety percent of all samples of this size will yield a confidence interval of (0.4977, 0.5023).
The 90% confidence interval is (0.3823, 0.4977). Ninety percent of all samples of this size will yield a confidence interval of (0.3823, 0.4977).
The 90% confidence interval is (0.3823, 0.4977). We are 90% confident that the true proportion of students attending the Valentine's Day Formal is between 38.23% and 49.77%.
