Students at a major university are complaining of a serious housing crunch. Many of the university's students, they complain, have to commute too far to school because there is not enough housing near campus. The university officials respond with the following information: the mean distance commuted to school by students is  miles, and the standard deviation of the distance commuted is  miles. 

Assuming that the university officials' information is correct, complete the following statements about the distribution of commute distances for students at this university.

(a) According to Chebyshev's theorem, at least  of the commute distances lie between 8.0 miles and 21.6 miles.


(b) According to Chebyshev's theorem, at least  of the commute distances lie between 4.6 miles and 25 miles.


(c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately of the commute distances lie between 8.0 miles and 21.6 miles.


(d) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 68% of the commute distances lie between  ___ 
miles and _____miles
