麻烦大家帮我看看这题:
The following data are items(in hours)between failures of air
conditioning equipment in a particular airlane:74,57,48,29,502,12,70,386
,59,27,153,26,326.Assume that the data are observed values of a random
sample from an expoential distribution,exp(θ).
(1)Find a 90% confidence interval for the mean time between failures,θ.
想不出来他的信赖区间该怎麽推导,请各位指教,谢谢了!
