Question 810708:

Question #8 / 20
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 11.0 miles and 23.4 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.)
(c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 68% of the commute distances lie between
miles
and
miles
.
(d) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately of the commute distances lie between 11.0 miles and 23.4 miles.
