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  17.5  miles, and the standard deviation of the distance commuted is  3.3  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  10.9  miles and  24.1  miles. (b) According to Chebyshev's theorem, at least  36%  of the commute distances lie between     miles and     miles. (Round your answer to 1 decimal place.)

Question
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 
17.5
 miles, and the standard deviation of the distance commuted is 
3.3
 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 
10.9
 miles and 
24.1
 miles.
(b) According to Chebyshev's theorem, at least 
36%
 of the commute distances lie between 
 
 miles and 
 
 miles. (Round your answer to 1 decimal place.)
