a) Let X1,. . . , Xn be the lifetimes of n electrical components of the same type. It is common to assume that the Xi are independent and Weibull (?, ?) -distributed, which we will also assume here. You can thus use some of the results from Exercise 2 in this task. We also assume in the whole problem that the parameter ? is known, while the parameter ? is unknown. A possible estimator for ? is then

that the Xi are independent and Weibull (?, ?) -distributed, which we
