The magement of a manufacturing plant is studying the number of times employees in a large population of workers are absent. A random sample of 25 employees is chosen, and the average number of annual absences per employee in the sample is found to be 6. The sample standard deviation is 0.6. Assuming the population of absences is normally distributed, construct a 99% confidence interval estimate of the population average number of absences.
