Assume that μ≥3λ . you observe the value t1 of the lifetime, t1 , of a lightbulb. a map decision rule decides that the lightbulb is of type a if and only if t1≥α . find α , and express your answer in terms of μ and λ . use ‘mu and ‘lambda" and ‘ln" to denote μ,λ , and the natural logarithm function, respectively. for example, ln2μλ should be entered as ‘ln((2*mu)/lambda)"."
