Question 8 A random sample of 30 students at a high school was allowed to play a popular cell phone game for an hour in order to score as many points as possible. The sample yielded an average score of 375 and a standard deviation of 100. The resulting 90% confidence interval is 375 +31. Which of the following statements best summarizes the meaning of this confidence interval? If we repeated this procedure many times, the average number of points scored by our sample of 30 students will be between 344 and 406 points approximately 90% of the time. o Approximately 10% of all students at the high school will score more than 406 points. o Approximately 90% of the students at a high school will have an average score between 344 and 406 points. o If we repeated this procedure many times, about 10% of the confidence intervals constructed will fail to include the mean number of points scored by all students at a high school
