A small New England college has a total of 400 students.The Math SAT is required for admission, and the mean score of all 400 students is 620.The population standard deviation is found to be 60. The formula for a 95% confidence interval yields the interval 640 ± 5.88.  Determine whether each of the following statements is true or false.

If we repeated this procedure many, many times, only 5 percent of the 95 percent confidence intervals would fail to include the mean Math SAT score of the population of all students at this college.
