Please solve all parts of 8.51
for a bus on a particular route is 300
minutes. Six buses are randomly observed and their
running times are recorded as follows: 320, 310, 295,
312, 302, and 308 minutes. Would you agree with the
transport company's claim? Assume a normal distri-
bution.
8.51 For an f-distribution, find
(a) fo.o1, when v = 12 and vz = 10.
(b) fo.o1, when vi = 10 and v = 12.

15 and v, = 8.
(d) fo.9s. when v = 10 and vy = 5.
(e) a99. when ey = 18 and = 14.
(c) foos. when v =
3D14.
