Ask Your Teacher Let X denote the distance (m) that an animal moves from its birth site to the first territorial vacancy it encounters. Suppose that for banner-tailed kangaroo rats, X has an exponential distribution with parameter 0.01387 6-15 P 4/5/2017Explanation / Answer
Solution:
= 1
a) mean = 1/ = 1
b) standard deviation = 1/ = 1/1 = 1
c) P(x 1) = 1 -e^(-1*1) = 0.6321
d) P(3 X 5) = P( x 5 ) - P(x 3)
= (1 -e^(-5*1))-(1 -e^(-3*1))
= 0.9932 - 0.9502 = 0.043
