The life time of a dryer machine can be modeled with the probability distribution , where x is the time in years and beta is an unknown parameter. Findings that 3 machines life time are after x1, x2, x3 years.
1. what is the likelihood function?
2. assume the observations are x1 = 5, x2 = 6, x3 = 5. Use this information and simplify the likelihood function as much as possible.
3. what is the log-likelihood function, simplified as much as possible for beta?
4. what is the maximum likelihood estimate for beta, use two decimal places?
