Question description
I just need help with the next two questions! 1. Using the χ2
distribution, find the following and draw the corresponding graph (with
the correct area under the curve shaded) :
(a) P(χα2
< χ2 < 22.307
) = 0.875 when ν = 15
2. For an F
distribution, find the following and draw the corresponding graph (with
the correct area under the curve shaded) :
(a) P (F ³f ) = 0.99 with n1 = 8 and n2 = 15.
(b) P (F ³f ) = 0.05 with n1 = 7 and n2 = 10.
(c) f0.95 (6,
10)
(d) P (F ³ 4.16) with n1
= 12 and n2 = 12.Thanks!
