Jim wishes to estimate the average number of days students are absent from his STA 205 in a semester. In a random sample of 36 of her STA 205 students the mean number of absences was 2.853 days with a standard deviation of 1.878 days. Find the interval that is three standard deviations from the mean. Interpret this interval using either the Empirical Rule or Chebyshev's Rule (whichever is most appropriate for this distribution).
