Question 437144: You have sampled 25 students to find the mean SAT scores at Morris Knolls High School. A 95% confidence interval for the mean SAT score is 900 to 1100. Which of the following statement gives a valid interpretation of this interval?
A. 95% of the 25 students have a mean score between 900 and 1100.
B. 95% of the population of all students at Morris Knolls have a score between 900 and 1,100.
C. If this procedure were repeated many times, 95% of the resulting confidence intervals would contain the true mean SAT score at Morris Knolls.
D. If this procedure were repeated many times, 95% of the sample means would be between 900 and 1100.
