Suppose that the interval between eruptions of a particular geyser can be modelled by an exponential distribution with an unknown parameter ✪ > 0. The probability density function of this distribution is given by f(x; 0) = 0e0¹, x > 0. The four most recent intervals between eruptions (in minutes) are ₁ = 32, ₂ = 10, 23=28, ₁ = 60; their values are to be treated as a random sample from the exponential distribution. (a) Show that the likelihood of 0 based on these data is given by L(0) = 0¹e-1300 (b) Show that L'(0) is of the form L'(0)=0³e-1300 (4-1300). (c) Show that the maximum likelihood estimate of based on the data is 0.0308 making your argument clear.

![Suppose that the interval between eruptions of a particular geyser can
be modelled by an exponential distribution with an unknown parameter
0 > 0. The probability density function of this distribution is given by
f(x; 0) = 0e 0¹, x > 0.
The four most recent intervals between eruptions (in minutes) are
x₁ = 32, x₂ = 10, x3 = 28, x4 = 60;
their values are to be treated as a random sample from the exponential
distribution.
(a) Show that the likelihood of based on these data is given by
L(0) 04-1306

(b) Show that L'(0) is of the form
L'(0) = 0³ e 1300 (4- 1300).
(c) Show that the maximum likelihood estimate of 0 based on the
data is ~ 0.0308 making your argument clear.
