A school system has assigned several hundred “chronic and severe underachievers” to an alternative educational experience. To assess the program, a random sample of 74 has been selected for comparison with all students in the system. One criterion for assessing program success is absenteeism ( the number of days missed per year). The sample mean for this variable was 5.04 and the population standard deviation was 1.86. Assume there was no extreme outliers in the sample. Construct a 95% confidence interval for the average number of days missed for all students in the program.
