statistics

A math instructor performed an experiment to compare performance on a year-end math test between students who were taught math using technology and students who were taught math using traditional methods. One hundred students taking were randomly assigned to one of the two teaching methods at the beginning of the year and were taught using the assigned method for the entire year. At the end of the year, all 100 students took the same year-end math exam. A 95% confidence interval for the difference in average year-end math scores (new methods - traditional methods) was (1 point, 4 points). Which of the following is a correct interpretation of this confidence interval? (note: some words are capitalized to indicate differences between similar sentences.) O With 95% confidence, the average score on the year-end math exam for all students taught with the technology method is between 1 and 4 points LOWER than students taught using traditional methods. O With 95% confidence, all students taught using the technology method will score between 1 and 4 points higher on the year-end math exam compared to students taught using the traditional method. O With 95% confidence, the average score on the year-end math exam for all students taught with the technology method is between 1 and 4 points HIGHER than students taught using traditional methods. O With 95% confidence, the difference in mean scores on the year-end math exam for the students observed is estimated to be between 1 and 4 points (difference taken was new method - traditional method)
