The numbers w₁, 2,..., w, are known positive values. The random variables X₁, X2,..., X, are independent, and the distribution of X, is N1,). Both parameters and are unknown. Find the maximum likelihood estimates of u and o². Is û an efficient estimator of u? μ c. An electronic system consists of four components connected in series as shown in the figure below. The components function independently and each one has a lifetime (in weeks) that follows the exponential distribution with = Find the probability density function of the lifetime of this electronic system and use it to compute the system's expected lifetime. 20* A 0000 d.
